Arrested Development (probably the best sitcom I've ever seen)
Curb Your Enthusiasm (Larry David's persona in this show is my hero)
Herman's Head (very quirky approach given the period, featuring two major Simpsons voices)
NewsRadio (extremely well-written and fun characters, also featuring a very early Joe Rogan)
The Office (UK) (the one that started all the spinoffs, monumentally cringe-inducing)
The Office (US) (some of the episodes excellent, some of them not so much, Robert California should have been the boss all along)
Review (quite obscure one, but unbelievably funny and different)
Seinfeld (pretty much any episode can be put on and one will not be disappointed, comedy genius)
