US - either Seinfeld or Curb your Enthsiasm (which are kind of the same thing)

UK - old school - Black Adder (all 4) and new - Peter Kay's Phoenix Nights - I loved that show

best:seinfeld.
worst:friends.

agreed- i now like to watch Joey just to see how horrific it is - its like watching a slow motion train wreck

Wonder Years
Fresh Prince of belair

Seinfeld

Its always been Seinfeld.

facts of life
desperate housewives
stacked
the simple life

beverly hillbillies ..or the dick van dyke show .. or the Lucy Show.

anything since makes me want to take a baseball bat to the TV


edit to add sanford and son ..
.. but it doesnt stand the test of time like the other 3 i mentioned.

Personally, I was a fan of Chico and The Man

Noticed a number of people have opted for Seinfeld but ive never got that show. Don't think ive laughed once when watching it.
