A little girl is out with her grandmother when they come across a
couple of dogs mating on the sidewalk.
‘What are they doing, grandma?’ asks the little girl.
The grandmother is embarrassed, so she says, ‘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?’ says the little one.
‘How do you mean?’ asks the grandma.
‘Offer someone a helping hand,’ says the little girl, ‘and they
fuck you every time!’
