A blond, redhead, and brunette were at the busstop making converstation while waiting for their separate buses. All three had discovered that they were pregnant in previous conversation.
The redhead looks to the other girls and says, "You know, I was talking with a good friend of mine and she said that the position you were in while the child was conceived may have something to do with the gender of the child. According to her, since I was on the bottom, it's a good possibility that I will have a boy."
The redhead looks over and says, "Well in that case, I'll be having a girl!" Meanwhile the blond starts hysterically crying.
"What's wrong?", the two ask while trying to console her.
"We're going to have a puppy!"
