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 embarrassed, 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 screw you every time ! "
