Do not fill this in!===Where Did The Idea Come From=== This episode is a commentary on genetic engineering and could be inspired by Dolly the sheep, the first successfully cloned mammal back in 1996. Many other mammals were cloned afterwards such as pigs, deer, horses and bulls. The character Shelley is based on Trey's sister who has the same name. When they were kids she regularly bullied him, once even tossing him down a flight of stairs. Stan wishing his mutant clone to attack Shelley is also based on Trey's childhood fantasy of a larger version of himself beating up his sister.
