Beetlejuice: 2x7

Dr. Beetle & Mr. Juice

Beetlejuice invents a cologne that changes the personality of anyone it comes in contact with into its polar opposite. When Lydia gets sprayed with it, she becomes a wild, prank-pulling criminal and, taking Beetlejuice along for the ride, wreaks more havoc on the Neitherworld than BJ’s ever been responsible for.
