The thing is, a lot of the humor in that movie is like not that funny when you first see it, but then a couple days later out of nowhere...

You know I felt the same way about The Big Lebowski. First time I watched it? Meh. But I kept remembering the quotes (granted the internet helped with that). So I watch it again and it's suddenly a totally new experience, like I'm finally on the inside understanding all the inside jokes.
