Well, just for completeness sake, those that I actually saw, liked and remembered (more or less) as being funny.
Monthy Python. Not sure if there is a *complete* series on DVD yet. Might have to check.
Fawlty Towers.
The Young Ones.
Red Dwarf.
And the above mentioned B.H. show.
The rest either didn't interest me or more likely never got aired in a place I lived.
One series deserves mention though for it's bizarre humour, even if it wasn't a dedicated comedy series and that was "The Avengers". Yes, I know, more a 007 type humour than slapstick, skit or sitcom, but occasionally hilarious none the less.
