Man, one of my all-time favorite shows. Hank and Artie were tops, but there was a butt-ton of talent on there (Jeneane Garafolo pops to mind).
I don't do a lot of comedy, but that's in there, along with Louie/Louis CK, late-stage Carlin, a few others. Oh yeah, and I loved Curb your Enthusiasm. Sinefeld was too sweet for me; Enthusiasm had the edge that I needed.
