Three pregnant women in a doctors office discussing what sex child they are having.

The brunet says "I'm going to have a boy because I was on the bottom when we made love".

The red head says, "Well that means I'm going to a have a girl because I was on top."

All of a sudden the blond burst out in tears. The two girls ask her what is wrong.

She replies, "I'm going to have a puppy".
