Between Two Ferns w/ Sean Penn

I admit that I'm a total fanboy of Zach Galifinakis. Followed him over the years and everything he does is gold...gold, Jerry! He's been doing a running bit of FunnyorDie.com called "Between Two Ferns w/ Zach Galifinakis" where he brings on famous people and interviews them between, well, two ferns. However, this time around we're blessed with Seth, Zach's twin brother for the interview. Seth and Sean Penn, I've already peed a little.
