Three pregnant women....

one brunette, one red-head, and one blonde...

are all talking about the sex of their unborn babies. The brunette says, "I heard if you want to have a baby girl, the woman must be on top during sex. That's what we did, so I know I'm having a girl." The red-head says, "I heard the same thing, but I wanted a baby boy and for that to happen, the woman must be on the bottom during sex. That's what we did, so I know I'm having a boy.

" The blonde starts screaming. When the other 2 women finally calm her down and ask her what's wrong, she sobs and says, "My boyfriend only likes doggy-style. I THINK I'M HAVING PUPPIES!!!"
