VIDEO: ‘Big Bang's’ Jim Parsons Strips for Cancer

Well, sort of. The actor dances in his skivvies for part of this funny new anti-cancer music video. It's for a good cause!

Cancer sucks. But this video starring Jim Parsons of CBS's "The Big Bang Theory" doesn't.

Proving Lorne Michaels really ought to ask Parsons to guest host "Saturday Night Live," Parsons plays no less than 30 different characters in the clip. It's a music video produced by the guys over at Stand Up to Cancer and features a song called "Up2 You + Me" from Zach Selwyn.

And yes, there are a couple of shots of Parsons in his underwear. Plus,”  a "Star Trek" reference.
