A blonde and a brunette are sitting in a bar and watching the 11:00 P.M. news. A man is standing on the ledge of a high-rise building, contemplating suicide.

The brunette says to the blonde: "I'll bet you $20.00 that the man jumps off that building and commits suicide."

The blonde thinks for a moment then replies: "OK, you're on!"

They watch for a few minutes and sure enough, the man jumps off the ledge. The blonde sighs and reaches for her wallet, but the brunette stops her, saying: "I can't take your money - I feel too guilty. I have to confess that I watched the 6:00 P.M. news this evening and I knew that the man would jump.

The blonde replied: "Oh! I watched the 6:00 P.M. news too, but I didn't think he'd jump off again!"
