Billie was playing a cornet and thought he was the only fellow making a noise. Oscar, his rival, however, was blowing a trombone in the near vicinity and the girl evidently preferred sonorous notes to light airy ones, as she picked Oscar and left Billie blowing flat notes. This made him sore and he attempted to throw Oscar into the creek. They both fell into a sand pile. Her ill feeling was not helped when Oscar got a job playing solos in the village meeting house which Billie had been trying to land for a month. Billie took a lemon to the concert, however, and when Oscar commenced his solo, Billie sat in the front row and squeezed the sour fruit. This so puckered Oscar's tonsils that he couldn't blow a note. The concert was upset and Oscar chased Billie onto the roof. Billie thought he was going to escape in the bell, but he didn't know Oscar was going to ring it from below. Neither did Oscar realize the roof was going to collapse when he chased Billie out on it. Also the girl did not realize the roof was going to fall on her, nor did the congregation want to get hit with plaster. But they all did.
