If you're an MMA fighter, you're pretty badass. You probably don't take much crap from anyone. No one is going to tell you what to do! Well, except maybe your dear sweet Mommy.

In the season finale of The Ultimate Fighter, Andrew Sanchez was really bringing the heat to Khalil Roundtree. Roundtree's mother was sitting ringside and was shouting helpful words of encouragement, but her baby boy did not appreciate the advice at all.

In the middle of the fight, Roundtree repeatedly shouted out, "Mom! Shut up!" Yeah, that's one of those things that'll get you mocked at in the locker room.
