Dotty Dripple; Horace Dripple; Mr. Jerkimer (Horace's boss)
Horace's boss, Mr. Jerkimer, asks him to buy an emerald brooch for Mr. Jerkimer's wife birthday. Horace gets the brooch, but accidentally puts it in an envelope containing bids for a city contract. The police come and arrest Horace and Mr. Jerkimer, thinking the brooch was a bribe for the city engineer.
Dotty, Horace, and the kids go to Market Utopia, a gigantic shopping center that's just been built. While the others shop, Horace falls asleep and has a nightmare about shopping in a store that's so big it crosses state lines.
