The "Force Seven" episode. In an odd attempt at a spinoff the episode focused on a secret unit of Kung Fu Cops, dedicated to the preservation of human life, that took on a terrorist organization. It even had John Rhys-Davies as the Big Bad.
"Mitchell & Woods" also qualifies; while the premise was a bit less bizarre compared to "Force Seven" (two female motorcycle cops become detectives), the episode mixes subject matter more serious than the typical CHiPs fare ( murder leading to a male prostitution ring) with an even higher level of camp than usual. It's basically a bad Dramedy version of Cagney & Lacey.
Season 6 episode "The Spaceman Made Me Do It" includes a young girl who robs a jewelry store after a person (or alien?) in a spacesuit telepathically tells her to do so. Despite evidence the "UFO" is just a helicopter, Ponch ends up believing it was really a UFO anyway. However, if it was really a guy in a spacesuit, how did she "hear" him tell her to steal the jewels?
Germans Love David Hasselhoff: The series was very popular in Mexico, thanks to the great voice acting work in the dub, and also Erik Estrada's performance.
Squick: Ponch's initial reaction when he realises he's getting a nude full-body Facetime from his CHP captain. He does admit later on that she's "tight". It's even implied that they might get together in some capacity.
