This is from a posting on the Freakonomics blog. This is just way too funny.
My favorite story concerns my son Nicholas:
Relatively early on in the pregnancy we had an ultrasound. The
technician said that although it was very early, he thought he could
predict whether it would be a boy or a girl, if we wanted to know. We
said, â€œYes, absolutely we want to know.â€ He told us he thought it would
be a boy, although he couldnâ€™t be certain.
â€œHow sure are you?â€ I asked
â€œIâ€™m about 50-50,â€ he replied.
Don’t take that technician to Vegas. He’ll having you picking numbers at roulette, and playing the horn in craps.
