a blond brunette and a red head are in the doctors office all pregnant.
the brunette looks at the other two and says, "im having a boy"
the other two ask how shes so sure of it, and she replies "well, i was on top"
So the red head says "well, i guess im having a girl sense i was on the bottom"
the blond bursts out crying and the other two try to consul her and ask whats wrong.
she looks at them through watery eyes and says.. "IM HAVING PUPPIES!!!!"
