What really used to impress me was a feature on IMDb in which people would write in with the vaguest descriptions of some scene they had stuck in their head.

"I remember a man walking down a hall, the lights flickering, and then a drop of water lands on his head." Or something like that. 9 times out of 10, one of the IMDb'ers could identify the movie. Amazing recall.

Nowadays, I think that letter column has been retired, but it appears that users are helping each other out with such questions on the IMDb message board I Need to Know.
