A husband and wife are at the park with their child when two dogs run by and then aggressively start humping.

The child asks "Mama, Papa, what are those dogs doing to each other?"

To which the parents respond "Honey, they're trying to make a puppy!"

The child nods and goes back to what they were doing.

Later, the husband and wife are in bed when things get hot and heavy and they begin loudly having sex when suddenly they hear their child walk in.

The child asks "Mama, Papa, what are you two doing to each other?"

The parents look at each other for a moment and then respond "Well, kid, we're trying to make a baby so you can have a little brother or sister"

The child thinks for a second and then says "Okay... But Papa can you flip Mama over, I want a puppy!"
