Those of you who are familiar with Arrested Development are probably well aware of the comedic genius that is David Cross. If you aren't, and I know that the show can be a little off-color sometimes, here's a great clip from the Mr. Show show that David used to be on. In it, he's the host of a TV call-in show that is taped a week in advance. Yes, it does seem a little complicated, and as you'll see the host is really having a rough go of things. Make sure to stick around til the end, where the comedy goes to another level.
Upon rewatching this, I really have to say I love the old man who just sits there through the whole thing, as well as watching the transformation of the host from the first show to the current show.
