Well the British aren't comedic geniuses either, so I can't blame Si. I don't understand the people who think that British comedy is like the epitome of comedy gold and can't help but quote Monty Python and Hitchhiker's Guide to the Galaxy. When it's funny, it can be really funny (Shaun Of The Dead), but falls on it's face for the most part according to this American. I always get a laugh when DJ sees me watching some comedy show he doesn't recognize that he finds to be strange and mostly unfunny, because he always asks "Is this British comedy?".
I'll stop now before I start getting mailbombs from overseas Commonwealth nations.
