A guy and his blonde date are at a bar, watching the 11 o'clock news on the TV. The news is covering someone who went out on a 20th floor building ledge and is threatening to jump.
"I'll bet you $20 that he jumps," says the guy.
"And I'll bet you $20 that he doesn't," says the blonde.
A few minutes later, the fellow jumps. The blonde takes out $20 and hands it to her date.
"I can't take your money," he replies. "This actually happened earlier and I saw it on the 5 o'clock news."
"I saw it too," replies the blonde, "but I didn't think he'd do it again."
