I can't remember the last movie I've seen myself (I think it was Schindlers List), but the last actual scene I watched was when I walked in on my dad whom was watching the Dark Knight. The scene where The Joker fires on a SWAT van with a rocket launcher during a car chase, and the Batmobile blocked it.
If that were happening around me right now... I would scream: "OMFG IT'S THE FRIGGIN' BATMAN!!", gasp for air, nerdgasm and faint, in that order.
