Watch Raul Rosas Jr. beat up, choke out YouTuber in prank gone wrong

Tread very lightly when trying to pull a prank on a UFC fighter - especially Raul Rosas Jr.

This is a lesson one YouTuber learned recently as he set his sights on the 19-year-old bantamweight phenom. A member of the TopNotch Idiots YouTube channel began his prank with Rosas on a treadmill at the gym, where things started to get heated. The prankster gave things some time to breathe after the action got separated, but then appeared in a room with boxing gloves on where Rosas was doing bag work.
