Plot summary
Jerry is surprised and titillated by an unidentified woman's voice sexually propositioning into a tape recorder he set up at his comedy act. Elaine confides in George that she recorded the voice to prank Jerry into believing someone in the audience was lusting after him. This secret knowledge of Elaine's lascivious side leaves George uncontrollably aroused. After jumping through hoops to order a Chinese baldness cure, George is torn between putting on the foul-smelling cream for his own sake, and taking it off for Elaine's. Kramer indulgently films everyone after getting a free camcorder.
