Having Babies

Two brunettes and a blonde are in the hospital awaiting the arrival of their first children. The 1st brunette says, "I just know I'm going to have a girl, because I conceived while I was on my back". The 2nd brunette says, "Mine's going to be a boy, because I was on top during conception". The blonde says, "Uh-oh! I'm going to have a puppy!"
