The episode "Band Candy," season 3, episode 6, has some hilarious moments as Buffy's Mother Joyce and Mr. Giles eat some magical chocolate candy and revert back to their teenage years, creating a Freaky Friday role-reversal situation for Buffy. Giles channels his inner-Spike as he seeks to impress the bad-boy crazed Joyce, and they make out (and more) while listening to old records. Soon they are joined by Principal Snyder, turned back into a teenage Geek by the candy, and he also wants to woo Joyce by doing some rockin' Tae Kwan Do maneuvers. It's all quite a bit of fun until they realize there are several small babies stolen from the local hospital by the Mayor and the Mr. Trick gang of vampires.
All the role reversals are great fun, and Buffy has to be the adult voice of reason for once.

One sad note - Giles listens to this song again in Season 5 "Forever" when Joyce dies.
