A guy walked into a bar right at 10:00 PM, sat down at the bar next to a blonde and looked up at the TV where the 10:00 news was covering a story of a man, on a ledge of a tall building, preparing to jump.

The blonde asks the guy, "Do you think he'll jump?"

The guy says, "I’d bet $20 he will."

The blonde replied, "Well, I don’t think he will; and, I’ll take that bet."

Just then the man on the ledge jumps off the building, falling to his death.

The blonde was very upset, but handed the guy 20 dollars.

The guy said, "I can't take your money, I saw this earlier on the 5 o'clock news and knew he would jump."

The blonde replied, "I did too; but I didn't think he'd do it again."
