Three pregnant women, a brunette, a redhead and a blonde, are all waiting in a waiting room to see their pediatricians for a check up. While they are waiting, they discuss the sex of their unborn babies.

” Mine is going to be a boy,” proclaims the brunette.

“How do you know this?” asks the blonde?

“My husband was on top when the baby was conceived,” replies the brunette.

“Mine is going to be a girl,” says the redhead in response.

“And how do you know this?” asks the blonde again.

“I was on top of my husband when the baby was conceived,” replies the redhead.

The brunette then asks the blonde “and what then do you think you’re going to have?”

The blonde then exclaims excitedly “Puppies!”
