Yeah man, I totally agree with that. The end liner was like, just perfect. I really expected the pipe that Franco climbed out of before the bomb went off to end up being a bong. lol That would have been good, but it wasn't necissary. Man, so many things made me laugh. The jokes were so well timed that if you were high it would probably be endlessly funny too.
I'm definitely getting this on bluray. It's the kind of movie you can watch again and again, unlike Superbad which was more funny for the shock humour (though hilarious in its own right).
