In a sport that requires two sweaty men to punch and claw away at each other to prove their worth, beautiful women holding up ring cards in between matches is the perfect compliment.
This phenomenon brings us back to 2007, when a certain Snickers commercial caused millions of viewers to wet their pants.

Once these girls do make their appearance, it's difficult to return to focusing on the match.
