I came to post about Greg the Bunny. I had forgotten about that John Larroquette bus station sitcom, but I used to watch it regularly when it was on the air. Good television.
Another vote for Undeclared and Clone High. Both damn hell ass hilarious, no question about it.
Some of mine have already been mentioned - Herman’s Head, Parker Lewis Can’t Lose and The Goodies - but how about Grosse Pointe? This show was very funny, but it ran for only one season. It also happened to feature William Ragsdale, otherwise known as Herman from Herman’s Head.
