Everybody Loves Raymond for me, great viewing in the morning... we have double episodes here in the UK from 07.30 onwards. I love Friends, but have seen each episode a million times. Surprised Frasier didn't get a mention here?
Seinfeld has never took off in the UK so not sure about it. Doubt it's in same league as Friends tho.
I would have to go with "Two & A Half Men" on their best days. For consistency of shows......I'd have to say "M.A.S.H" (Alan Alda)......incredible comedy & very good social commentary too.
I watched Seinfield a couple of times before but didn't really like it. My all time favorite and one of the most famous tv shows is FRIENDS. How can someone not love it? I have all the seasons on DVD and i have watched them all several times. still not bored of it and never will be.
