At some point, Tim got married.
In the episode "Underage Drinking: A National Concern", Mac and Charlie get back at Dennis by telling him that Tim Murphy slept with his prom date, much to Dennis's upset.
- Season One: Underage Drinking: A National Concern (mentioned only)
- Season Seven: The High School Reunion, The High School Reunion, Part 2: The Gang's Revenge
- Frank rightly said about Tim: "Seems like a nice guy".
Dennis: "I'm gonna bang Tim Murphy's black wife."
