From The Royal Tenebaums:

Richie: I wrote a suicide note.
Chas: Can we read it?
Richie: No.
Chas: Can you paraphrase it for us?
Richie: I don't think so.
Chas: Was it dark?
Richie: Of course it's dark. It's a suicide note.

I just love that line, cracks me up every time.

But the best line in a movie is definitely the "I love the smell of Napalm in the morning" that Cow mentioned. Brilliant line.
