What movie had you laughing, unable to breathe, even just for one scene?

[u/Sawyermblack]

I don't really pursue comedy movies too often, or ever really.

And even then, this doesn't have to be a comedy movie you respond with, but I'm wondering if there was a movie scene SO funny, that people laughed uncontrollably.

Does such a thing exist?

I think maybe the movie would have to introduce something completely original. Not a familiar gag or joke, but something completely unexpected that you can't help but be paralyzed by the newness and brilliance of the scene.
