My favorite comedies are "Liar Liar" "Animal House" "Theres Something About Mary" and "Caveman". What are yours?
I lean a bit to quirky so some of these are a wee bit on the dark side but off the top of my head:
An Everlasting Piece (about hairpieces in 80s Ireland)
The Taste of Tea
My Cousin Vinny
Seven Psychopaths (with brilliant performances by Sam Rockwell and Christopher Walken)
Oh, and in a nod to the season, Shaun of the Dead.
If we're talking films specifically, ever since I was little I've loved Harold Lloyd's silent movies, which still hold their own after a century. More recent choices are Amélie and Les Triplettes de Belleville.
As for TV series, Monty Python's Flying Circus has to be towards the top of the list (though as was pointed out on Family Guy, approximately 90% of it is neither clever nor funny); so too do Look Around You (a brilliant pastiche of 1970s Open University lectures on TV), golden era Simpsons, The Fast Show (which I believe was called Brilliant in the US) and the extremely dark comedies Monkeydust and JAM.
I loved "Les Triplettes de Belleville." I need to do a re-watch soon.
