Chris Weidman
Fomer UFC Middleweight champion Chris Weidman went in disguise to International Fight Week in Las Vegas back in 2016 so that he could play a prank on the many MMA fans in attendance.
Weidman got fully into character as a janitor at the UFC expo, complete with wig, nosepiece, fat suit and dodgy facial hair, which left fans bemused as she shuffled around making a nuisance of himself.
Weidman then started heckling fans who were getting a chance to practice in a makeshift Octagon setting and eventually indulged in a playful sparring session with one fan before finally revealing who he really was.
