Semi-autobiographical, Come Blow Your Horn is the story of young and inexperienced Buddy Baker, who leaves his parent's home to live with his "ladies' man" older brother, Alan. Both Buddy and Alan work for their father, who sells wax fruit. Buddy wants to write plays for television or the theater. His father says wax fruit provides a more stable future. ''Plays can close," he tells Buddy. "Television you turn off. Wax fruit lays in a bowl till you're a hundred.'' Add to this mix a mother who is adept at emotional manipulation and prone to hysterics, and several several serious and casual girlfriends, and the stage is set for fireworks all around.
