A blonde, a brunette and a redhead where in the doctors office. All three of them were pregnant. 'I'm having a boy,' the brunette said. 'How do you know.' asked the other two. 'Because I was on top,' was her reply. 'Well, I'm having a girl,' said the redhead. 'How do you know,' asked the other two. 'Because, I was on top,' was her reply. The blonde starts sobbing hysterically. The other two try to calm her down. 'Sweetie, what's wrong,' asked the brunette. 'I'm having puppies,' cried the blonde.
