All vaudeville comedy acts were dependent, in some part, on stock materials for inspiration. Stock materials include jokes and song parodies; monologs—strings of jokes or comic lectures; bits—two- or three-person joke routines; and sketches—short comic scenes, often with a story. To these stock materials comedians add what cannot be transcribed in words, the physical comedy, or the “business”—the humor of inflections and body language at which so many vaudevillians excelled.
