Sean Penn is the latest celebrity to appear on Funny or Die‘s Between Two Ferns hosted by funny man, Zack Galifianakis. Or more accurately, this one is hosted by Zack’s brother, Seth as Zack is away on ‘adult fat camp!’

If you’ve not heard of the show then you need to check out the previous ones which you can see here. The basic premise is that Zack Galifianakis interviews a celebrity and completely ridicules them live on camera. It really is comedy genius, and this one with Sean Penn is no different.

You have to give it to the celebrities for being good sports to go onto this spoof TV programme and when they give some come-back, it’s awesome!
