Little Joey was walking through the park with his mother when he saw two dogs mating,"What are they doing mommy?" he asked astonished.
"Oh, honey they're just making puppies." explained the mother.
That night, awakened by loud thumps and squeaks, Joey went to his parents room where he spied them having sex. "What are you guys doing?" he asked, wide-eyed.
Startled, his mother stammered. "Why, we're just making a baby."
Joey's eyes lit up, "Dad,roll mom over, I'd rather have a puppy!"
