Sometimes liquid courage is a terrible, terrible thing.

One guy had WAY too much to drink in Vegas recently, and instantly regretted it. He was far past drunk, when he decided to start yelling and screaming at his waiter. He was causing quite the scene and someone had to shut him up.

That someone just happened to be a UFC Hall of Famer.

Yep, but the drunk dude had no clue.

After yelling at the waitress, he took a swing at another costumer. That costumer was none other than UFC legend Matt Serra, who was in town for his hall of fame induction ceremony.

Honestly, the drunk guy got off easy. Serra simply subdued the man and pinned him down until security arrived.

You have to see this!
