The First Hat: Sam Selwyn's, of course, you couldn't mistake that ultramodish block. Sam lived in great style, butler, and all that sort of thing. Mrs. Sam ruled the roost; he got his first chance to be gay when she took daughter to visit mother. Fred Bellamy had just come to spend a few days with Sara. "We'll make a night of it," Sam declared. "Nothing of the sort," said Fred, "I'm going to see Lottie Blithers." The Second Hat: Bosco Blithers, like his hat, was a trifle seedy. Lottie couldn't keep papa from the cabarets. But she wasn't lonely that night when Fred called. Bosco came tiptoeing home and was caught. He had to promise to let her marry Fred, whom he had never seen. One thing troubled him in a collision with several other exhilarated gentlemen he had lost his hat. It would never do for Lottie to find him out. The Third Hat: Thompson was the name on the band, and there are a lot of Thompsons in the directory. Sam Selwyn got this hat by mistake and, in distress, he sent Fred out to look up all the Thompsons. He had given a cute little lady Fred's name as a safeguard, and when Lottie sent Fred a note Sam was in panic lest Mrs. Sam find him out. Then Lottie herself came, and Sam locked her in his room. She kicked the door down.
