They're getting tougher now that most of the Will Ferrell and Jack Black scenes are gone. My votes:
#1 - Sixth Sense. Great scene. I'd tell you more, but it's a major spoiler. This scene is quite entertaining.
#2 - Blues Brothers. I don't really think of this as a great scene, but for some reason it's always better than its competitors. Maybe I'm underrating it.
#3 - Tombstone. Fine scene, fine mustaches.
#4 - Pulp Fiction. He died of dysentery? Wear that watch proudly.
#5 - The Dark Knight. I don't get it. Does Batman have a cold or something? Why is he so hoarse? And where's Robin?
Vote for Winona.
