Mike Tyson may have been heavyweight champ of the world but that doesn’t mean he can bust a move. The ex-boxer revealed some less than stellar dance moves on Thursday’s “Lip Sync Battle.”

"Iron" Mike performed Salt-N-Pepa’s classic “Push It” which was disappointing in that he kept forgetting to do it  but he made up for it with his enthusiasm and extremely tight pants.

Tyson faced off against former NFL star Terry Crews who delivered a moving rendition of Vanessa Carlton’s “A Thousand Miles,” which his character on "White Chicks" famously sang. The performance started with Crews seated at a piano and then ended with the former Rams player ripping off his white blazer and pumping his pecs in time to the beat. Judging by the crowd's reaction it looks like Crews punched out Tyson.
