Blonde Bet

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 10:00 PM news was coming on. The news crew was covering a story of a man on a ledge of a large building preparing to jump.
The blonde looked at Bob and said, 'Do you think he'll jump?' Bob says, '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 6 PM news and so I knew he would jump.'
The blonde replied, 'I saw it too; but I didn't think he'd do it again.'
Bob took the money......
