The Simpsons

As co-creator of "The Simpsons," Sam Simon amassed an epic collection of memorabilia ... which you can own, if you got the cash.

Simon's estate teamed up with Sotheby's for "The Creative Genius of Sam Simon: A Lifetime of Memorabilia," to auction off serious 'Simpsons' swag, and stuff from his other sitcoms he wrote and produced.

Sotheby's tells us the most sought after items include one of Simon's drawings of Bart, expected to go for $1,500 ... and an animation cell from an episode, estimated to fetch $2,000.

The crown jewel might be concept drawings of 'Simpsons' characters from the early planning stages of the show. Sotheby's thinks that will pull at least $5k.

Matt Groening is literally living a Joni Mitchell song ... his neighbor paved paradise and put up a parking lot, and he's pissed.

Matt is enraged one of his neighbors is taking an ax to four 100-year-old pine trees, which he says are on protected property.

The "Simpsons" co-creator says the neighbor wants to pave over the area to accommodate her cars.

The Santa Monica neighborhood is up in arms. Bobby Shriver, the former Santa Monica mayor and member of the Kennedy clan, along with his wife, Malissa, tried to stop the chainsaw massacre by protesting to the City of L.A. Turns out, the trees are on the border between Santa Monica and L.A. and the stumps rest on the L.A. side.

One neighbor, Jerry Rubin, actually chained himself to one of the trees in protest.

Matt and company won a temporary reprieve ... the City of L.A. ordered the tree hackers to stop until they determine conclusively whether she has a right to chop the pines down.

As they say ... you don't know what you got till it's gone ...

"The Simpsons" creator Matt Groening has been sued by his former nanny, who claims he has it out for Hispanics, even though Matt's wife is Hispanic.

Tania Cardona claims in a new lawsuit, obtained by TMZ, Matt and his wife treated employees "like animals," claiming she was not only worked to the bone, but harassed over her heritage.

Cardona says Matt would say his son was not going to speak "good English" because there were so many Hispanics in the house. The lawsuit says Groening would complain, "his house looked like a Hispanic community and he 'hated' it."

Cardona grouses she and the other Hispanic employees had to eat at a small table next to a trash can in the laundry room.

It's a puzzling lawsuit, because Matt is married to Agustina Maria Picasso Achaval, who is from Argentina.

Cardona claims she was wrongfully terminated and wants millions in damages.

Harry Shearer could come back to "The Simpsons" after all, because we've learned both sides want to make it happen .... but there's still a major hurdle.

Harry said Wednesday night his negotiations with producers had broken down and he would not come back to the show. Producers said they were moving on and finding new people to do Harry's voices.

But James L. Brooks, the exec producer of the show, just tweeted, "Hey, we tried. We're still trying. Harry, no kidding, let's talk."

And we just spoke with sources directly connected with Harry who told us, "It was difficult for him not to come back. He loves all 23 of his characters. If there's a way to work this out and continue to have a career in addition to 'The Simpsons' he would be delighted."

So the door is open, but our sources say Harry and producers are at loggerheads over Harry's ability to do other projects. Our sources say Harry has more restrictive language in his contract than other cast members. They say producers bent a little, allowing him to do other things if they agreed.

We're told Harry and his lawyer, Larry Stein, would not agree to giving producers the right to veto Harry's other projects.

Every 'Simpsons' fan's worst nightmare just came true -- Harry Shearer ... one of the key voices on the show is leaving after contract talks broke down.

According to Shearer ... co-creator and executive producer James L. Brooks' attorney broke the news that Harry would "not be part of" the show going forward.

TMZ broke the story ... Shearer was the last cast member left to sign on for the 2 year extension FOX recently announced. Our sources said the 71-year-old actor had issues with the back end and merchandising parts of his contract, and refused to sign.

On Twitter Wednesday night, Shearer said the breakdown was because he wanted "freedom to do other work."

It's a major blow to the longest running scripted show on TV. Shearer voiced neighbor Ned Flanders, Principal Skinner, Mr. Burns, Smithers, Kent Brockman ... and a ton of minor characters. In all, he's given voice to well over 100 citizens in Springfield.

"Simpsons" creator Matt Groening took issue with our story that there's a major holdout in the cast, but we know it's true, and now we know who.

Groening told our photog Saturday night all the actors have signed on for the next 2 seasons. Fox has already announced the renewal.

But sources intimately familiar with the production tell us Harry Shearer, who voices multiple characters on the show, has not re-resigned. As we reported, all members of the cast make the same amount per episode, but we're told Shearer still has issues with back-end and merchandising and Fox does not have his signature.

Fox has announced "The Simpsons" -- which has run 26 seasons -- is coming back for another 2, but they may have jumped the gun because we've learned one of the key players has not signed on.

Sources close to the production tell TMZ the holdout has not reached an agreement. The sources would not say which actor is holding out, but we're told it's a key person in the mix.

We're also told the people who have signed on have all agreed to the same amount per episode and that is not an issue with the holdout. The sticking points in the past have had to do with back-end profits and merchandising.

Pamela Anderson got a lavish gift from Sam Simon just weeks before he died, and ironically the show of affection is the very thing that has made her persona non grata at his private funeral.

Pam and Sam have been tight for years. We're told a couple of weeks before the co-creator of "The Simpsons" succumbed to Colon Cancer, he gave her a ring worth around $800,000.

Sources who were close to Sam tell us his family was infuriated and felt Pam took advantage of a weak man and should never have accepted the gift.

We're told they have specifically decided to exclude her from Tuesday's private service.

Sam Simon's cherished 3-year-old dog is heartsick over his owner's death, but there's already a new owner who is doing everything he can to ease the blow.

Tyson Kilmer, one of Sam's close friends who is also a dog trainer, tells us shortly after Sam was diagnosed, he called with a request -- love and cherish his Italian mastiff after he died.

Tyson gladly obliged, especially because of his history with Columbo. He trained the pooch for aggression issues when he was a pup.

Tyson had a plan he put into motion months before Sam died. Columbo spent time at Tyson's home so the permanent move wouldn't be too jarring.

We're told Columbo is adjusting well, but misses his dad. Kilmer took one of Sam's favorite hooded sweatshirts and laid it on Columbo's bed ... which the dog snuggles up with at night.

Good news ... Columbo has a girlfriend ... a pit bull named Kasha Fierce.

The biggest adjustment for Columbo ... moving from Pacific Palisades to Sherman Oaks ... woof.

Sam Simon, the co-creator of "The Simpsons" has died ... TMZ has learned.

Simon passed away Sunday at his L.A. home, following a long, difficult battle with colon cancer. Simon was diagnosed in 2012 and was very public that his disease was terminal.

We're told Simon was surrounded by his family when he died, and his dog. The dog was very special in Sam's life ... he was a big animal rights advocate.

The Sam Simon Foundation tells us, "For those of us who knew him, his voice will forever echo in our minds; his sense of humor will continue to make us laugh; and his compassion and generosity will continue to impact our lives."

Adding, "Sam, you will be missed by many, but there is a particular sadness among our clinic staff. We have been together for so long, and your absence will forever leave a void in our lives."

Hank Azaria, who voices multiple characters on the show, just tweeted, "Rest in peace and thank you for The Simpsons, Sam Simon."

Sam previously announced he would be leaving his nearly $100 million fortune to his various charities.

Simon was 59.

Matt Groening can draw Bart Simpson doing anything -- and he can do it in his sleep -- so if you say "make it interesting" when he's doing a custom sketch for you ... buckle up!

"The Simpsons" co-creator was doodling for a few fans at JFK this week, and one guy got way more than he expected. If you've ever wondered what a strung out, crack alley version of Bart looks like ... wonder no more.

Homer Simpson has NOT been stuck in a coma since the '90s ... despite a fan theory that has thrown "The Simpsons" fans for a loop -- so says the show's executive producer.

The idea -- first posted on Reddit -- theorizes Homer's been in a coma since a 1993 episode where he was hospitalized. The fan theory is that he never woke up, and everything that's happened ever since was a dream ... but Al Jean tells us NOT TRUE.

Al explains, "It would mean back in 1993 we would presume the show was going on for years and years more and right before we left, threw this hidden monkey wrench in for all our successors," adding, "I’m afraid it goes with the 'Dead Bart' episode in the intriguing but false file.”

The creator of "The Simpsons" says Smithers was color incorrect when he first appeared on the show ... black.

Waylon Smithers' black hue was simply a mistake, but producers didn't have the money to turn him to his intended yellow ... so says Matt Groening.

Groening gives an interesting explanation for the error, which was short-lived. It was corrected for Smithers' second appearance in the town of Springfield ... whatever state it's in.

Groening also tells us why all the other characters are yellow ... and it's not what you'd expect.

"The Simpsons" pulled off a major heist when the mafioso character Louie rolled into Springfield -- and now a "Goodfellas" star wants a cut of the action.

Frank Sivero played Frankie Carbone in the classic 1990 film ... and says "The Simpsons" created a Carbone copy of that character when Louie first appeared in an episode entitled "Bart the Murderer" on Oct. 10, 1991.

Louie, who is Fat Tony's henchman on "The Simpsons" ... is hardly a regular. According to Sivero's lawsuit against FOX, the character appeared in 15 more episodes between his debut and April 27, 2014.

In the suit, obtained by TMZ, Sivero says he lived in the same apartment complex as some of the 'Simpsons' writers back in '89 ... and they knew all about the character he "created and developed" for 'Goodfellas.'

To the naked eye ... Louie does look like a dead ringer for Frankie.

Former NASCAR driver Leilani Munter WILL be taking her "Blackfish" car to Talladega, TMZ has learned -- all thanks to an incredibly generous donation from "Simpsons" co-creator Sam Simon.

As we reported, Leilani had desperately been trying to raise money to pay for the $115,000 fee to enter the car for a big race at an ARCA event at Talladega Superspeedway on May 3rd. As of our last story, she had raised only $7,500.

But that all changed last week -- Leilani appeared on Simon's radio show to talk about her car and orca-related activism ... and Simon was so moved, Leilani tells us, he donated the balance of her entrance fee immediately after the show ... $107,500.

We're told Simon visited Taiji in February (the place where "The Cove" was shot) and has become an outspoken advocate for the humane treatment of orcas. Leilani tells us, she plans to win the race on behalf of orcas around the world suffering in captivity.

Sam -- who has terminal colon cancer -- has vowed to give away his fortune before he dies ... specifically toward animal rights and feeding the hungry.

As if giving the world "The Simpsons" wasn't enough.

It's always darkest before the dawn -- "Family Guy" might have taken away our beloved Brian Griffin ... but Kelsey Grammer tells TMZ, Sideshow Bob WILL be making a triumphant return to "The Simpsons."

KG was out in L.A. this week when we got to chatting about Brian's death ... and conspiracy theories about the dog's return ... and Kelsey says Sideshow Bob ALWAYS comes back. "They've already killed him 20 times. He comes back a lot."
