learned how incredibly easy it is to turn garbage (waste ethernet cables from work) into money. I rented a uhaul and took 6 pallets of old ethernet cables to a wire scrap yard, and split the returns 3 ways with the 2 cable puller guys I was working with. Next time, I won't need to bring them...
I don't get to many games either (none this year, even). That's what makes the bet fun. If you lose, you have to go to a game, but you do it in a jersey the winner bought for you...so no matter what, everyone wins (and loses).
But if you just want to make it a boring beer bet, that's fine too.

I think the foobar abx methodology is seriously flawed. Quickly shifting back and forth like that doesn't provide much of an opportunity to catch subtle differences.
