Bob walked into a sports bar around .
He sat down next to a blonde at the bar and stared up at the TV.
The news was coming on.
The news crew was covering the story of a man on the ledge of a large building preparing to jump.
The blonde looked at Bob and said, "Do you think he'll jump?"
Bob said, "You know, I bet he'll jump."
The blonde replied, "Well, I bet he won't."
Bob placed a $20 bill on the bar and said, "You're on!"
Just as the blonde placed her money on the bar,the guy on ledge did a swan dive off the building, falling to his death.
The blonde was very upset, but willingly handed her $20 to Bob.
"Fair's fair. Here's your money."
Bob replied, "I can't take your money. I saw this earlier on the news, so I knew he would jump."
The blonde replied, "I did, too, but I didn't think he'd do it again."
Bob took the money.
