This makes me laugh every single time I read it...
Bob, a handsome dude, walked into a sports bar around 9:58 pm. He sat down next to a blonde at the bar and stared up at the TV.
The 10 pm 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 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 5 pm news, and so I knew he would jump."
The blonde replied, "I did too, but didn't think he'd do it again."
