best movie mistakes of all time

this is the best reason to dust off all those old dvd's and start watching them again.
this site has a list of the best movie mistakes of all time and also has them listed for this week if you want to go see them in the theater and watch for the mistakes.
i dunno, the best one i ever saw was in 'three men and a baby' back in high school, there's a scene where they're shooting in a nursery room where, legend has it, a young boy killed himself years earlier and the camera pans past the rocking chair and sees nothing but upon the second pan back, the boy can be seen in the corner.
creepy... but false....
