In 1979 or '80, our Commodore PET user group had a booth at the PNE
(Pacific National Exhibition) in Vancouver, BC.
One of the programs running was a cribbage game. We had one fellow who
monopolized it for a couple of hours, and decided that the program was
cheating, as it won about 50% of the time, and he considered himself to
be much better than that. One of our members asked him if it seemed like
the cards dealt to him were biased toward the machine. He said no, but
felt that the machine pegged better.
I'm not sure we convinced him.
I know a guy who's addicted to brake fluid.
He says he can stop any time.
