Three pregnant women are sitting in a cafe having lunch, when one of them says, "I know that I'm going to have a boy."

The other two women think about that for a moment, and then one of them says, "OK, how do you know you're going to have a boy?"

"Well, when the child was conceived," says the first women, "I was on top. So I'm going to have a boy."

They sit and eat for a few minutes more, and then the second woman says, "Well, I'm going to have a girl."

"OK," says the first one, "how do you know you're going to have a girl?"

"Well, when my child was conceived, I was on the bottom. So I'm going to have a girl."

They sit and eat for a few minutes more, the third woman obviously getting more and more distressed, until finally she breaks down into horrible sobbing?

"What's wrong, what's wrong?" the first two women ask with concern.

The third woman manages to stifle her sobs long enough to only say one thing....

"I'm going to have a puppy!"
