Payman sends an interesting nugget:

I was listening to the Commentary Track on an episode of "Mr. Show" Season 4 on the DVD, and the guys mentioned that Charlie Kaufman wrote a spec script to apply to be a writer for "Mr. Show." They didn't take him on, but it would be really interesting to see if anyone had that script.

Indeed. If there really is a Kaufman-scripted Mr. Show skit floating around, we'd love to take a look. As always, I can cover copying and postage, unless you want to scan or PDF it and email it along. Same goes for any of his other work that we don't already have.
