Mayweather vs. Pacquiao -- Tickets Sell Out in 60 Seconds

And just like that ... THEY WERE GONE!!!!

Less than 60 seconds after tickets to the Mayweather vs. Pacquiao fight went on sale to the public on Ticketmaster's website, they were sold out!!

ALL OF THEM.

EVEN THE $7,500 TIX!!!

Several people in our office timed the sale, and some say they got the "No Tickets Left" graphic less than 20 SECONDS after it started. Insane!

So, if you wanna be at the fight, you have to go to the secondary market ... where seats are going for up to $80,000-a-pop!!!

Good luck!
