The Courtship of Joseph's Father
Cops and Robert
Peggy is depressed that her birthday always ends up being a bust, so she vows to plan the party of the year. Hank, Bill, Boomhauer, Kahn, Luanne and the rest of the gang gather to celebrate with a disco-themed shindig on a mystery train, and everyone gets dressed in their sharpest 70's (jobs) attire, featuring everyone from Andy Warhol to Grace Jones. When Luanne ruins the mystery it becomes clear this is just another typical Peggy party. However, when a couple tucks away to the train's bathroom for some extracurricular activity, a new mystery unfolds and the gang tries to find out who "had relations".
- It is revealed that Peggy has never once had a good birthday.
- The title refers to "Strangers On A Train," a 1950 mystery novel by Patricia Highsmith that was made into a motion picture the following year by Alfred Hitchcock.
- As the actors enter the train car which has been named after the New York City nightclub Studio 54, the music is the opening of the song "Disco Inferno" by The Trammps.
Hank: "A Chubb Randolph production."
Hank: The railroad commission also regulates propane.
