National Lampoons Anthropomorphic Vacation
One time Clark Griswold wanted to go on a vacation.
"Yo, dorks, let's go on vacation."
"Where to, dad?" Said Clark's son Rusty.
"The zoo, faggot," replied Clark.
"Bitchin' dad, I love the zoo," said Clark's daughter Audrey.
"I love the zoo so much, I'm rock hard." said Ellen Griswold, the wife and mother of the family.
"Let's fuck then," said Clark.
"Tubular," said Rusty, who was actually a lemur.
Clark, a bengal tiger, began unbuckling his belt, revealing his massive cock.
Audrey, who was a giant spider monster from space started sucking her father's genitals.
Ellen then dropped her dress, revealing her lithe, muscular, flamingo body, and commenced having hot sex with her sun.
Everyone had hot incest sex.
