It reminds me of my SCUBA training. The head instructor had a list of offenses. If you committed an offense (i.e. leaving goggles on forehead after surfacing), he'd say, "6-pack," obligating you to bring a 6-pack of beer. ;-)
Some of the other offenses:
* Breaking the build (unit tests only) and then leaving for the day without fixing it or reverting your change
* Walking away without logging out of your machine (very security-conscious business)
* Not completing an assigned code review within a week of being assigned (within reason -- if the code review was enormous, or you were overly busy with an enormous project of your own, don't worry about it)
I once sent out an email from a co-founders account which said that he was fed up with the crappy codebase and was hiring a new team to rewrite it from scratch and that the other (non-tech) co-founder was to take over the existing tech team. No one took it seriously (non-tech co-founder helped me draft the email, the other one laughed while reading it after the fact), but there was a board member in the mailing group who thought it was serious and started sending panicky emails to the co-founders.
