The titular door turns up as a running gag during the climactic "Side Show" segment. Elsewhere, Archie and Moose demonstrate some new water-skiing techniques; Professor Jughead offers a few lessons in agriculture. Sabrina teaches the kids a magic trick involving a glass and a coin. Coach Cleats participates in such curious sports as rocket-powered barrel jumping, tall-tree diving and the Boot Hill Motorcycle climb. And in the "Little Archies" segment, it's Archie vs. Reggie in a sled race. This "Fun House" episode first aired in 1969 as a segment of The Archie Comedy Hour. ~ Hal Erickson, Rovi
