Little Suzie was walking with her grandmother when they saw two dogs having sex. "What are they doing, Grandma?" asked the little girl. Grandmother was embarrassed, so she answered, "The dog on top has hurt his paw and the one underneath is carrying him to the doctor." Suzie considered this a moment and then asked, "Dogs are just like people, aren't they, Grandma?" "How do you mean, Suzie?" "Offer someone a helping hand and they'll screw you every time!"
