StandUp2Cancer

As Dr. Sheldon Cooper on 'The Big Bang Theory,' Jim Parsons is a big bang of funny week in and week out. Oh, yes, he's not working alone. He has a wonderful group of actors around him and they're also very funny characters. But the breakout star on that show from the very start has been Jim.

But is it the character or the actor? Hmm ... if only there was a way to see Jim doing something else. Well, ta-da, here it is. Watch this public service announcement created by the folks at Stand Up to Cancer. If you had any doubt that Jim Parsons is a comic wizard, this will dispel them.
