Head of the Class/Trivia


 * The Danza: Billy Connolly as Billy MacGregor.
 * Dawson Casting: Dan Schneider was born in 1966. You do the math.
 * Tony O'Dell was born in 1960. Dan Frischman, playing one of the students, was born in 1959, making him 27 years old when the series began.
 * Basically most of the cast other than Tannis Vallely (Janice), who was the first one to leave (she was really smart).
 * Written by Cast Member: "Will The Real Arvid Engen Please Stand Up?" was the first writing credit for Messrs. Robbins and Schneider. It would definitely not be the last.
