Favorite Movie Ending

[Posneg]

Some movies wouldn't be how good they are if it weren't for their endings. Name a movie where you thought the ending really made it good, or you just loved it, or whatever...

I can't get over the ending of Quentin Tarantino's Deathproof. I'm talking about the very end...

Spoiler (Highlight to read):

---

where they kill Stuntman Mike, and all three girls jump up in the air

---

It was so unexpected and it made me laugh so hard. I honestly think it couldn't have been better than that.

Does anyone else want to elaborate on that, or share their favorite endings?
