Camp Winnicooper for the Deaf is a special summer camp for deaf children.
In "An Apocalypse to Remember", Stan Smith was fooled into thinking that all of civilization had been destroyed due to a nuclear holocaust, and took his family into the woods, leaving behind Roger and Klaus. After Roger calls Stan on his cell phone and tells him it was just a drill, Stan doesn't tell his family the world hasn't ended and doesn't want them to know that he goes searching for food at a summer camp.
Determined to be quiet while slipping in past a pie eating contest, he accidentally makes as much noise as humanly possible until he realizes the children are deaf. When he gets caught, he is chased by the campers who the family mistakes as mutants due to their pie-covered faces.
