Bob walked into a bar, sat down next to an attractive blonde and stared up at the TV. The 10pm news was airing the story of a man on the ledge of a large building preparing to jump.
The blonde looked at Bob and asked "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 the ledge did a swan dive off the building, falling to his death.
The blonde was very upset, but willingly handed her $20 to Bob, saying, "Fair's fair. Here's your money."
Bob replied, "I can't take your money. I saw this earlier on the 6pm bulletin, so I knew he would jump."
The blonde replied, "I did too, but didn't think he'd do it again."
Bob took the money...
