A Roflmao blonde joke!

There were 3 women siting in the waiting room of their OBGYN and all were pregnant. And about 5 months along. First the brunette says,"I heard that if you're on bottom, you will probably have a boy." Then the red-head say,"Yeah well I heard if you were on top you are having a girl!" And then all of a sudden the blonde lady burst out in to tears, crying uncontrolably! The other two ask her what was the matter and she she replied sadly," I think I am having puppies!"
