What are the 3 reasons that Bud was given the band nickname Sleep LaBone

The band members adopt a professional tone and nominate different titles for Bud. “Sleepy” is too simple and “the Bone” too blase, but finally they decide on “Sleepy LaBone,” which is the best name Bud’s ever heard. Mr. Jimmy pretends to announce him to a crowd, and they have him kneel and mock-knight him. Bud can barely contain his excitement, and plans to practice four hours a day to live up to his new name.
