Synopsis by Hal Erickson
Laura (Mary Tyler Moore) is surprised to come across a crumpled letter in Ritchie's pants pocket, requesting that Rob (Dick Van Dyke) show up at his son's classroom the next day for a "Father of the Week" presentation. Much to Rob's chagrin, Ritchie (Larry Mathews) doesn't want his dad to come to school, feeling ashamed that Rob is "only" a TV comedy writer whereas all of his classmates' dads are jet pilots, policemen, and the like. His pride wounded, Rob insists upon showing up for the classroom presentation, where after suffering the unintentionally insensitive introduction by the teacher (Isabel Randolph) he scores a surprising hit with the kids. This episode was inspired by "Head of the Family," the original unsold pilot for The Dick Van Dyke Show starring series creator (Carl Reiner) as Rob Petrie.
