In The Shining, when Jack Torrance has clearly gone mad and is chopping down the bathroom door with an axe to get to his wife, why does Jack Nicholson say "Here's Johnny!" when his character's name is Jack? Is it completely random and showing how he's gone so insane he's just saying random names, or does it have some sort of significance?
That line was ad-libbed by Jack Nicholson as an imitation of Ed McMahon's intro for The Tonight Show.
