"Road to Europe"
Season 3, Episode 20

As Kiss superfans, Peter and Lois attend the first night of Kiss-stock dressed like the band members. With a ton of leather, numerous metal studs, and Peter rocking a hybrid ponytail/top-knot, the couple are glam'd out rockers who would give Gene Simmons and crew a run for their money as best-dressed rock stars. Unfortunately, Lois doesn't know any of Kiss' lyrics, proving that she walks the walk, but can't talk the talk.
