A bet is a bet

A brunette and a blonde met in a bar after work for a drink, and were watching the 6 o'clock news. A man was shown threatening to jump from the Brooklyn Bridge. The blonde bet the brunette $50 that he wouldn't jump, and the brunette replied,
"I'll take that bet!" Anyway, sure enough, the man jumped, so the brunette gave the blonde the $50 she owed. The blonde said "I can't take, you're my friend". The brunette said "No. A bet is a bet". So the blonde said "Listen, I have to admit, I saw this on the 5 o'clock news, so I can't take your money". The brunette replied, "Well, so did I, but I never thought he'd jump again!"
