I have to hang my head in shame and admit I'd never seen it (clips, yes, but the whole movie, no).
I only realised I hadn't when I started watching it late on Thursday night.
What a brilliant movie! I can't remember laughing as much at a film for years. I particularly loved it when there were two funny things happening independently in the same scene, and the suicide scene laid out as The Last Supper.
That's a proper funny movie, not like most where they try to spread 15 minutes worth of jokes over an hour and a half.
