Top Secret!

I know this is an old movie, but I saw it recently to remember. It is crazy, funny, crazy, funny and crazy. I can't really find any other adjective suitable to it. It has a story (a vulgar one, is true), it has some sarcarm regarding other movies (and that is really cool), and a lot of laughs. Basically you can't stop laughing from the start. It is true that in some situations you really need to look around and not just to the main actors to understand why you are not laughing at that moment.

If you never saw it, go out and buy or rent it. Yes, now!! NOW!
