Warren Buffett hit in Las Vegas this weekend.
While at the MGM Grand for the Floyd Mayweather fight, the billionaire investor decided to bet on a sports book for the first time ever.
Buffett saw the line that had Nebraska favored over Fresno State by just 12½ points. So he put $550 on Nebraska.
A few dozen other people saw Buffett make the bet and immediately went running to the window to place the same wager.
Nebraska won in a 55-19 blowout, making Buffett (and his new friends) just a little bit richer.
