Andy Samberg Vs. Andy Sandberg -- Haters, Get It Straight!!!

You'd think having the name Andy Samberg has its perks -- after all, the 'SNL' vet just hosted the Emmys -- but it's turned a namesake into a target of hate.

Andy Sandberg, a Tony Award-winning producer, says his Twitter account has been flooded since Sunday night by haters who went on a mission to trash Samberg for his jokes about Donald Trump and Kim Davis.

Turns out Samberg the comedian doesn't tweet from his own Twitter account ... he uses The Lonely Island account. The real problem here ... people don't know how to spell Samberg's last name.

It's been going on for years ... Sandberg says he gets Samberg's fan mail and pleas to audition for "Brooklyn Nine-Nine." He's even gotten a residual check ... but he didn't open it.

Sandberg also says he barely watched the Emmys. Join the crowd.
