So back before..well, the internet really...I used to write down my daily bets on a little corner of notebook paper and rip it off so it was a perfect square, and then fold it in half. When my grandpa died one of the few material things I got was this little angel artifact. I used to put my daily bet sheet under the angel for the day for good luck (and also to hide from the wife).
One day I lost a bet, I remember what it was, I had TOR +6.5 against the spurs and it went to OT and they were down 6 and sure enough those dumb motherfuckers fouled and lost by 8 in OT and I chucked the angel across the room and the head came off. I proceeded to go on like a 1/17 streak...true story, swear to God. I even tried to super glue the head back on, still a curse.
