Cheek Week

Cheek Week is a porno magazine.

History
Sideshow Bob slipped away from a prison detail, stole an atomic bomb, and hid out at a nearby Air Force base. When the authorities looked for him at the base they found only some porno magazines: Granny Fanny, Cheek Week and American Breast Enthusiast. When Krusty came over to the base, he said "Hey-hey, now this is my kind of meeting!".
