On the Spike show "Lip Sync Battle," which is a fun, goofy show that I don't watch but understand the appeal of, because I am very broad-minded and all, Mike Tyson battled Terry Crews and put in what may be the worst lip sync performance in the history of televised lip synch performances, other than perhaps Ashlee Simpson on "SNL." Remember that? Remember that person?
Here's Mike doing Salt-N-Pepa's 1988 classic "Push It":
The good news is that Tyson is having fun, and that's the real point of it all, unless you're some kind of genius like Anna Kendrick or whatever. Also Mike appears to know the words at various points, but mostly he's just into the dancing part. And the "simulate oral sex with your fingers and tongue" part.
The final shot is probably a bit more lewd than that, though:
I'd say this is a new entertainment low for Tyson, but he was also in the Hangover sequels, so if anything this is probably a step up.
