Season 10 Opening Cast Listing:
Clarence, Arnold's cook, makes his on-screen debut.
This is Linda Purl's first appearance as Ashley Pfister. This is also Heather O'Rourke's first appearance as her daughter Heather.
Fonzie's "black book" is the size of a regular address book (in this episode), but in "Fonzie Moves In," his address book consists of two three-ring binders, and in "Fonzie's Funeral (2)", his address book consists of two filing cabinets.
A small door has been built into the Arnold's kitchen entrance for small cook Clarence. However, he has been working there since the days of the original drive-in, and the door has never, ever been there before.
