There was a blonde, brunette, and a red head in a doctor's office. All
three
of them were pregnant. All of the women were just talkin about how
excited
they were about being a mommy. First the red head said, " I'm gonna have a
boy
because i was on the bottom." Then the brunette said, " I'm gonna have a
girl
because i was on the top." The two women looked at the blonde. She had a
big
frown on her face. She said, " OH KNOW!!! I'M GONNA HAVE PUPPIES!!!"
