Two guys in a bar are watching the TV. There is a news report about a man who threatens to jump off a 5 story building unless the cops give him 3000 dollars. One guy at the bar says to the other:
"I bet you 100 bucks the guy jumps."
The other guy takes the bet, and the guy on the TV ends up jumping. The guy hands over the 100, but the winner gives it back, saying that he had already seen the guy jump on the earlier showing.
The loser says,"Well I saw it too but I didn't think he would jump again"
