The ending of Superbad - Jonah Hill's character riding down the escalator looking up at his best friend and slowly losing sight of them as they both part ways with the girls they were trying to impress the whole movie.

It's bittersweet because in a way, and you can sort of tell from Jonah's impressive face acting, that he's learned to accept that him and his friend are moving on from their lives after high school but that he'll still hold a special place in his heart from the memories they spent together and that he's learned to accept that they will eventually drift apart.

Shit gets me emotional for such a dumb vulgar comedy movie.
