Pirates of the Caribbean (The Curse of the Black Pearl) - Dog Bone
In the scene where jack Sparrow is in jail, he tries to pick the lock with a dog bone. He hears Will Turner coming down the stairs, so he immediately sits back down, leaving the bone in the keyhole. After a long conversation with Will, Will proceeds to lift the door up with a bench. For a split second, you can see the keyhole. There is no bone in it, even though no one removed it.
A good memory
