Married with Children, speciaifically the era with Steve cause once Jeffereson came into the picture the whole newlywed vs old married dynamic was lost.

Simpsons, I know its still going but the first seasons will always outshine the newer stuff. Simpsons was great until every episode either became about Homer being more ridiculously stupid than usual (seriously watch the series in order, you'll notice his IQ drops significantly with each new season) or about Lisa going off her usual political activism.

I love Kids in the Hall, but that was more of a sketch comedy series so I can't count it. The Critic was a wonderful and poorly received series, but damn if I didn't love it. It still has one of my favorite jokes in television:

A bunch of terrorist are walking into a New York City theater with machine guns and anti-aircraft weapons

Theater employee: Who are you?

Terrorist: Um...we're caterers!

Theater employee: Aren't you a little heavily armed to be caterers?

Terrorist: Um... we took the subway?

Theater Employee: Aren't you a little lightly armed to be taking the subway?

Frasier is good before Miles and Daphne got together but beyond that, I'm not big into sitcoms. I never liked Seinfeld beyond a few episodes, can't stand Roseanne or Coach. 3rd Rock from the sun is mostly hit or miss. Fresh Prince was alright but Family Matters was a little too touchy feely for my taste. Never really watched the Cosby Show.
