Guess Who This Lil' Dude In Stripes Turned Into!

Before this lil' dude in stripes turned into an actor and singer, he was just having fun with improv comedy in Cali, and gearing up to be featured in several funny films ...

He stars as the nerdy teen in "Superbad" and even tapped his talents into an evil villain persona in "Kick-Ass."

Need one more hint? He may have something to do with a fake Hawaiian organ donor ID!
