Bob and the Blonde

Bob walked into the bar around 5:58 PM.
He sat down next to a very attractive blonde at the bar and stared up at the TV.
The 6 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 reckon he'll jump." The blonde replied, "Well, I bet he won't."
Bob placed a $20 note on the bar and said, "You're on!"
The blonde placed her $20 note on the bar, and kept watching the scene on the telly.
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 "Fair's fair, here's your money."
Bob replied, "I can't take your money". I saw this earlier on the 5 PM news, so I knew he would jump."
The blonde replied, "I did, too, but I didn't think he'd do it again"
Bob took the money.
