When I was in college, some gals in the dorm were messing around wth the OB. They asked it stupid girly stuff like who whould take who to the dance, etc. But one thing was interesting, although it could be coincidence. They asked it who would be the highest scorer at the next college basketball game. It said "Lorne (not his real name)." After putting the board away, the girls were saying that Lorne would not be the one. They seemed to be confident that they knew the members of the team and their performance history to know that it would not be Lorne. We all went to the game, and Lorne scored the most points.
I have heard horror stories galore about OB's. Some were on this board. Maybe there are invisible beings (not demons) who can tell if you're scared and mess with you. I wonder if they could make Lorne score, too.
