Three party girls gather at Charley's apartment. He's hosting a party for three councilmen from Rockaway in hopes of selling them some property. While the women powder their noses, the men arrive, but instead of the councilmen, it's three dour gentlemen from the trade association. Charley tells the call girls to act refined, so one of them suggests a game of post office. Will the straight-laced men figure out these aren't a librarian, college administrator, and music student, and is Charley's sale about to be washed away in a stream of seltzer?
