Really sorry for the triple post (they are on different days!) but I feel its a crime if I dont sing the gospel of the Jason Mantzoukas & Andy Daly episodes of Comedy Bang Bang. I've been going through them all and I honestly dont remember laughing this hard and prolonged for a long time. The jist is Jason is intereviewed for about 10 minutes and then Andy Daly interrupts him in character and then that character is interviewed for the remainder of the show by Scott and Jason. I believe the whole thing is improvised as well. So you'll have Scott and Jason asking Daly questions to trip him up and make him laugh. Its really great though because Jason is so friggin funny and quick. I think anyone who likes Jason on HDTGM will want to hear this.
The episodes that I can confirm are hysterical are 74, 131, and 200.
