Incoming UFC Hall of Famer Matt Serra exacted his mixed martial arts expertise on an unsuspecting, rowdy drunk man in Las Vegas on the Fourth of July holiday.

Serra posted a video of the end of the altercation and explained how the patron was harassing restaurant staff. The man even tried to throw punches at the former UFC Welterweight champion (Warning: Post and video contain NSFW language):

According to TMZ Sports, Serra was at the Grand Cafe at Red Rock Casino when the situation escalated to the point some fool had to be subdued.

Probably a bad idea for someone to pick a fight with a mixed martial artist in Serra who was nicknamed “The Terror” during his UFC heyday. His professional MMA record stands at 11-7 with five victories by submission (h/t Sherdog).

Consider this drunken man in Vegas submitted. Even at 44 years of age, it appears Serra has still got a little bit of the expertise that made him a force in the Octagon.
