So, I've become a little obsessed with
fitbit.
My employer started a "pilot" program "Walking Challenge". As part of this program, employees of the company were given discounts on fitbit trackers. The company also paid $50 for each fitbit bought through the program.
Then, each person who wanted to join the program was divided into a team. There were something like 550 people divided into 22 teams across 3 locations (I work for a big company).
When I got my team assignment, I started talking trash with a couple of my co-workers and told them my team was awesome and theirs sucked. We made a wager between our two teams. I was putting up homebrew. I don't really remember what the other team wagered.
Unfortunately, after starting off fairly well, my team (Team 7 ... Take a Hike) has really sucked. The other team (Team 8 ... Happy Feet) isn't doing a whole lot better, but they are doing better enough that it does not look like we will catch them.
