There is a hat hanging on a coat rack along with a coat that Bugs Bunny and Daffy Duck hide in.
The hat changes positions on the coat rack from one side to the other.
The pack of matches is full when Giant Elmer starts smoking Bugs and Daffy out, but is empty after Giant Elmer uses four of them. A standard pack of matches contains 20 matches - to match the number of cigarettes in a standard pack of cigarettes.
