I appreciate all types of humour, but where I'm from where generally known as funny people, as we make fun of ourselves and everything else. But we also like good clean, clever humor.
I guess you could also pose the question of what comedian, writer, show, or movie epitomizes humour from each country?
For example:
Britain: Monty Python, The Office, Dame Edna, Absolutely Fabulous, Benny Hill
Canada: Wayne and Shuster, This Hour Has 22 Minutes, Kids In The Hall, Jim Carrey
Ireland: Dylan Moran,
USA: Saturday Night Live, Porkies (or American Pie for you kiddies), George Carlin, Robin Williams, Bill Hicks, Jeff Foxworthy, Dane Cook (I'm kidding. No one finds Dane Cook funny)
