Tom and Jerry Growth

In the Tom and Jerry cartoon 'The Incredible Shrinking Cat" Tom and Jerry wind up in a castle where a mad scientist creates a remote which enlarges using the red ray and shrinks using the blue ray.  While he goes out to buy some cheese and some bread, Tom and Jerry play around with it and shrink and enlarge each other until Jerry drops the remote and it enlarges Tom and makes him big and fat.  Then Tom takes the remote and makes Jerry bigger and fatter than himself.
