I generally hate comedies with a laugh track, but can't help it because almost all have it. "Frasier" was a nice exception as only the pilot episode had it. Frasier also happens to be one of the most smartest comedy shows I have seen. It is often masterfully built around one big joke, that is developed very carefully and gradually from the beginning. Just pure genius.
I was surprised to see "On the Buses" mentioned, considering how old it is. But I suppose it reruns quite often at least in British television. In my country they don't much rerun local shows, not to mention foreign shows. I remember liking it when I was a child, but that's about all I remember.
Other British shows I like are "Yes, Minister" and its sequel "Yes, Prime Minister". They really help me to understand how the real world works
From older American shows "All in the Family" and "Married... with Children" are my favorites. I kind of like when people can say and do offensive things on purpose or accidentally, and just laugh it off. Something that I would like to have in real life as well.
With more recent (like last twenty years) shows I really can't say to remember anything exceptionally standing out. "Friends", "Big Bang Theory" etc. sure had something in them, but they never really hit me with their awesomeness. "Scrubs" perhaps stands out - when you realize that it is actually more accurate and realistic portrayal of hospital life than most of serious hospital drama series on TV (it annoys me to see same person to do initial examination, give standard vaccination, and perform surgery during same work shift - I'm looking at you ER...).
Edit: Show is "All in the Family", not "Those were the days"... Latter one was the title song, not show title.
