The title of this episode refers to a character called The Jimmy who constantly refers to himself in the third-person in addition to making odd-looking athletic shoes. When Kramer attends a benefit for handicapped adults, fresh from getting Novocain at the dentist's office and decked out in a pair of The Jimmy's shoes, crooner Mel Torme mistakes him for one of the guests-of-honor. Meanwhile, Elaine inadvertently finds herself making a date with The Jimmy, George's sweating makes him look guilty at work, and Jerry suspects the copies of Penthouse magazine in his dentist's waiting room have affected the behavior of the doctor and his assistant. Bryan Cranston, later of FOX's Malcolm in the Middle, reprises the role of dentist Tim Whatley and "The Velvet Fog," Mel Torme, appears as himself. Originally airing March 16, 1995, "The Jimmy" was the 17th episode shot for the show's sixth season, despite being the 18th one shown.
