Where I worked they decided to have a lottery syndicate.

We had to put a lot of pressure on to one nitwit who thought 1,2,3,4,5,6 was a good idea, pointing out to him that it stood no better a chance of winning and at the time, with the estimated number of people choosing those numbers, a win would just be a few hundred pounds.

I think those numbers are second in the list of most common passwords.

Bookie's odds on holes in one dropped dramitically after that episode.
