Out with Grandmother

“What are they doing?” asked the girl. The grandmother was embarrassed, so she said: “The dog on top hurt his paw, and the one underneath is carrying it to the doctor.”

The girl thought for a moment, and then said: “They are just like people, aren’t they?”

“What do you mean?” asked Grandma.

“Offer someone a helping hand,” said the girl, “and they will fuck you every time.”
