The One With The Road Trip

Al receives a ransom note indicating that a well-known spaceship from his planet has been stolen. To get it back, he and Harold must go to Alabama and retrieve it themselves. They're not really sure how to do this... or even how to get to Alabama. They pack up Harold's car and Harold's cat and start driving south. They encounter catnappers, more aliens, and their own kids along the way. And it isn't until they reach Tuscaloosa that they realize the FBI has been following them since DC.
