From The Blonde Files

Jack, a handsome man, walked into a sports bar around 9:58 pm. He sat down next to this blonde at the bar and stared up at the TV...
The 10:00 news was 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 Jack and said, 'Do you think he'll jump?' Jack says, 'You know what, I bet he will.' The blonde replied, 'Well, I bet he won't.' Jack placed $30 on the bar and said, 'You're on!'
Just as the blonde placed her money on the bar, the guy did a swan dive off of the building, falling to his death. The blonde was very upset and handed her $30 to Jack, saying, 'Fair's fair... Here's your money.' Jack replied, 'I can't take your money, I saw this earlier on the 5 o'clock news and knew he would jump.
'The blonde replies, 'I did too; but I didn't think he'd do it again.' Jack took the money..
