The showdown with Drago at the end of Rocky IV.
I really can't describe this scene properly, so I'll just say when Neo and Trinity get past security and just start shooting the whole fucking place up (in slow-motion to boot) in the first Matrix.
The scene where Patrick Swayze was giving dancing lessons to Baby in Dirty Dancing.
(I'M KIDDING!!!!!!!!!!!!!!!! So, don't even bother ripping me for this! lol).
