Creatures of the Night - S2-E21
Factual error: Mike and Kelly are at the theater watching "Rocky Horror Picture Show" in 1977, talking during the song "Sweet Transvestite." After the line "satanic mechanic" and the audience callback "S and M.", which is only about two thirds of the way into the song, the music suddenly crescendos and ends, to be replaced by the song "Touch-a Toucha-a Touch Me," which occurs several scenes further into the movie.
