I must admit, years ago, I'd have said the same - but i think American comedy has really come a long way since those days. There's been some really great American comedies .... I liked Frasier (of course) & Ali McBeal & Sex In The City was cool. Also loved Six Feet Under though I guess that's not really a comedy per se (Though I do agree with you Glenr re Scary Movie etc though the original was okay)
I do love British comedy though, Dad's Army & Fawlty Towers are of course, classics, , also liked Red Dwarf, but also there's been some great more recent stuff like Drop The Dead Donkey (admittedly quite old now), Peep Show & Nightingales.
Re MySpace .... In case anyone's interested, I think my MySpace address is shown at the bottom of my posts though it's actually my music myspace page.
