Plot summary
Jerry tells George and Elaine that insurance would cover his physical therapist massages if he got a fraudulent doctor's note from his dentist, Roy. George gets a massage from a handsome male masseur, but is paranoid that he may have felt sexual pleasure, and questions his own sexuality. Roy (Ralph Bruneau) writes fraudulent notes for all three of them, and ends up investigated for insurance fraud. The group doubts Kramer when he vividly describes a sighting of Joe DiMaggio dunking a donut.
