6x20 "The One with Mac and C.H.E.E.S.E."

Joey gets his hopes up over his first significant acting job since Dr. Drake Ramoray. He has the part of science fiction hero Mac Machiavelli, the crime-fighting partner of a cool robot, C.H.E.E.S.E., which stands for Computerised Humanoid Electronically Enhanced Secret Enforcer. Monica bursts into the apartment making Chandler forget to finish a note for Joey that his decisive second audition has been moved two hours earlier. The friends reminisce about other instances when they have messed up. By miracle Joey gets another chance, which Chandler writes down correctly.
