Jill and Jenn want to take their younger brother, John, to the Zoological Gardens. There is just one problem, neither of them are old enough to act as a chaperone for their younger brother. So the girls invented a fictitious uncle, Jim, that they disguised themselves as. Jill was the actress of the family so she sat upon Jenn's shoulders who acted as Uncle Jim's legs. John saw his sisters in their new guise and burst out laughing, but promised to help promote the masquerade the girls were pull off. It was the only way they were going to get in after all.
