If you think that is freaky, I got one that is sports related.
Back when I was in college, my friends and I were watching the Redskins play in the commons room. Well, one of my friends said, "I hate Joe Theismann, I hope he breaks his leg." Of course, a couple of plays later, Joe got the hit that busted his leg and ended his career.
My friend turned three shades of white and felt so bad that for three days he would ask "Did I do that?"
Just goes to show - be careful what you ask for, you might just get it.
