Oh, the joy of themed Mad Libs.

One day, Little Brown Riding Hood was going through the forest carrying a basket of toilet paper rolls for her grandmother. Suddenly, she met a big, smelly wolf. "Crap!!!!" said the wolf. "Where are you going, little dookie?"
"I'm going to my grandmother's house," she said. Then the wolf dumped away. When Miss Riding Hood got to her grandmother's house, the wolf was in bed dressed as grandmother. "My, Grandmother," she said, "What big toilets you have."
"The better to flush you with," said the wolf.
"And Grandmother," she said, "What big turds you have."
The wolf said, "The better to wipe you with."
And then she said, "What big farts you have, Grandmother." But the wolf said nothing. He has just died of indigestion from eating Grandmother.
