A blonde and a brunette were watching the 11:00 pm news. The current
news story was about a man up on a ledge and threatening to jump, when the station cuts to a commercial.

Brunette: I bet you $20 he’s going to jump.
Blonde: OK.

(Back to newscast : He jumped!)
Blonde: OK. I lost. Here’s my $20 to you.
Brunette: No, that was too easy. I can’t take it.
Blonde: I insist. I lost.

Brunette: I have a confession to make. I saw the same thing on the
6:00pm news and I knew he jumped. So it wasn’t really a good bet.

Blonde: I know. I saw the same newscast at 6 too. But I didn’t think he would be stupid enough to jump TWICE!
