When you hear don't judge a book by its cover. It is actually true.

A Brazilian man tried to rob a woman over the weekend thinking he was going to get away with an easy score. Come to find out that the woman he was robbing was, in fact, UFC fighter Polyana Viana.

Viana was waiting for her Uber ride outside a Brazilian night club when the misguided robber noticed her. He approached her, then demanded her phone and any money she had on her. After the robber said he had a gun the UFC star began to punch and kick the would-be robber and put him in a rear naked choke hold. Ouch.

The gun that the man said he had was a fake cardboard cutout. Then after the beat down the dude begged her to call the police. Smart move.
