While buying 99's engagement ring, Max unknowingly stumbles on a robbery and receives a huge diamond from Mr. Spiegel to keep it out of the thieves hands. The diamond is worth $250,000, so the Chief suspects Max of stealing the diamond. With 99, they return to Spiegel's Jewelers and find two bald men searching the place for the very diamond Max got the day before. They trick Max out of the diamond, but he follows a clue to a bowling alley and The League of Bald-Headed Men.

Mr. Spiegel is played by Dick Wilson, who also was Mr. Whipple of Charmin fame.
