I don't have netflix and find it incredibly difficult to not recommend something in the holy Linehan trilogy (Or Fawlty Towers, The Young Ones, Red Dwarf, The Thin Blue Line), but one sitcom I'm enjoying a lot this year is Brooklyn Nine Nine.

EDIT: I guess though if you don't like Scrubs you won't like that either, so I suppose I'm not much help today.

When I was younger, I enjoyed Just Shoot Me, Two Guys & A Girl, The Cosby Show and Seinfeld - one of those has to be on Netflix.
