Larry and Jeff meet with an inventor about an idea that he wants funding for. The invention is a car periscope for drivers to be able to see ahead of the traffic in front of them.
LD and Jeff also attend a party in NYC and Larry meets a famous judge from tv. Upon meeting him, Larry finds a one-armed man playing Scrabble with the judge. The one-armed man was destroying the elderly former judge, but when the judge's son comes in the room, the one-armed man had left so Larry was blamed for it.
While trying out the prototype for the car periscope, Larry and Jeff find the one-armed man on the street, but he ends up getting away. When they finally catch him, later on in the episode, the one-armed man bumps into the judge, and knocked him over. The man gets into a cab, and Larry with his arm now in a sling, is blamed for it.
