Bob walked into a pub at around 9:58 p.m. He sat down next to a blonde at the bar and stared up at the TV. The 10 p.m. news was coming on.
They were covering the story of a man preparing to jump off the ledge of a large building. 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 note on the bar and said, “You're on!” Just as the blonde placed her money on the bar, the bloke 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 7 o'clock news, so I knew he'd jump.”
The blonde replied, “I did, too, but I didn't think he'd do it again.”
