Tim touches one of Martin's antenna, and is thrown into the fourth dimension: he becomes invisible and is in limbo. Martin finds a small crack into the dimension but it's getting smaller and smaller as time goes by. He thinks that Tim can make it through with a running start, but Mrs. Brown comes by the apartment with the handyman and won't leave, which doesn't allow Tim to come through. Meanwhile, the crack closes. Martin goes to Plan B: he remembers that Tim will be able to get out of limbo by actually doing the limbo under a burning broomstick. Despite his fears about being cooked like a goose, Tim tries it as it's his only option.
