how you know you've seen a movie too many times

Rocky and I were watching TV last weekend when a show began with the camera panning over a jungle.

Rocky: "That's Rush Hour."

Me: "How do you know?"
Rocky: "I know the music."
Me: "What?" (It sounded like generic instrumental music.)
Rocky: "It's Rush Hour 2."

Then the camera passed over the forest and a dense city emerged, and Jacky Chan's name appeared on screen. I gave him a look.
