A little girl was out with her Grandmother when they came across a
couple of dogs mating on the sidewalk.
"What are they doing, Grandma?" asked the little girl.
The grandmother was embarrased, so she said, "The dog on top has hurt
his paw, and the one underneath is carrying him to the doctor."
They're just like people, aren't they Grandma?" said the little one.
"How do you mean?" asked the Grandma.
"Offer someone a helping hand," said the little girl, "and they fuck
you everytime!"
