And yeah, those shows must all BLOW if Chappelle's Show, surely half of which sucked, is the fourth best of all time.
(I had the DVDs for both of the two actually-aired seasons, but only watched through them all the way about twice.)
MadTV had a funny sketch where an obnoxious rude Jewish track suit wearing rich middle aged guy visited a doctor and took off his robe at the end of the sketch to reveal he was wearing a really big disgusting nude prosthetic body prop. The crowd's reaction was very funny. Aside from that I never recalled laughing once at it.
Think how long Bob Odenkirk toiled away on so many of these shows and now Saul Goodman is going on his tombstone.
The British show Alfresco from 1983-84, starring Emma Thompson, Hugh Laurie, Stephen Fry and Robbie Coltrane, was not on the list, and wasn't mentioned in the entry for A Bit Of Fry And Laurie. I guess it's not that well remembered? I watched some of it and found (unsurprisingly) that most of the references went completely over my head.
What I know about Your Show Of Shows is that it's often repeated, falsely, that Woody Allen wrote for the show. Allen was born in 1935 and could not possibly have been writing for a show that was over with before he was 20. This is an even lamer urban legend than people repeating that Citizen Kane was the first movie to show ceilings.
