The melody itself is "Gaudeamus Igitur," an old Latin tune, we probably know best as the basis for Johannes Brahms' finale to his Academic Festival Overture. It is the pomp and proper feel that helps set up the humor of this setting. Lyrically, it's a simple joke with a cute punch line: I dropped my kazoo on the floor and now I'm stuck playing this drum. The basic melody is performed twice, first singing and then playing it on kazoo. (from Music K-8, Vol. 25, No. 5)
