See if you can find "Crossballs", it was a panel debate show where they'd call in two legit "experts" to debate comedians pretending to be legit experts. Andy Daly was a regular on there.

... You know, it will work better if you just watch:

Hey! That's Matt Besser! Also a great improviser. The Improv4Humans podcast is pretty great most of the time, and the Andy Daly episodes are very entertaining.

I just put that episode of "Crossballs" in the hopper, vote it up please.

he's also consistently incredible on the comedy bang bang podcast (and show.) On one amazing episode he makes all of his recurring characters commit suicide.

That is my second favorite appearance by Andy Daly on Comedy Bang Bang. My favorite is when he's the Limerick guy and they are trying to all make each other "read" Limericks from the book.
