Dawson Casting: Largely averted for the main cast. One notable exception was Julie Condra, who guest-starred as a high school freshman at age 20. This made the story arc where Condra's obviously older, sexually mature character comes on to innocent young Kevin Arnold rather jarring.
Fake American: Olivia d'Abo. You know, Karen Arnold. Wait... you did remember that Kevin and Wayne have an older sister, didn't you?
Germans Love David Hasselhoff: The series was pretty popular in Mexico during its broadcasting tenure, to the grade many of their voice actors had become celebrities (especially Kevin's younger and adult versions and Winnie's Mexican voice actors).
Keep Circulating the Tapes: The large amount of hit songs featured in the show — and the corresponding legal and financial snags involved with licensing the rights to all of that music — make a proper, uncut DVD release of the show nigh impossible. Netflix and Amazon eventually secured streaming rights, but these still have edits to the soundtrack that include soundalikes and even an alternate version of the theme. In February 2014, it was reported that a complete series box set, with most of the original music retained, was being prepared for future release by Time Life/StarVista Entertainment.
Missing Episode: The first of the shows two clip shows is not available for viewing on Netflix.
