On my "Bounties Earned" page, one of them is a bounty that I'm listed as earning 0 points on being awarded, "Can I use Google Analytics to sort out the statistics of my iOS app?"
Except, I was the one who offered the bounty, so I couldn't have awarded it to myself, and certainly could not have been awarded 0 points.
(But, I did end up being the accepted answer; that could be a factor here, too).
