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, ‘cuz I conceived while I was on my back".
The 2nd brunette says, "Mine’s going to be a boy, ‘cuz I was on top during conception".
The blonde says, "Uh-oh! I’m going to have a puppy!"
