Anytime anyone comes out of the water, his/her hair and clothes are always completely dry minutes later.

When Don walks up with his friends, Charlie has three girls hanging off of him who are all dancing, yet in the following shot they are all, very suddenly, dead still.

Before Larry removes the scroll from the frame, he places his flashlight on top of the frame. After the guard passes, Larry reaches down and picks up the flashlight from the floor.
