$50 Bet
A blonde and a redhead 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 redhead $50 that he wouldn't jump, and the redhead replied, "I'll take that bet!"

Anyway, sure enough, he jumped, so the blonde gave the redhead the $50 she owed. The redhead said "I can't take this, you're my friend". The blonde said "No. A bet's a bet".

So the redhead said "Listen, I have to admit, I saw this on the 5 O'clock news, so I can't take your money".

The blonde replied "well, so did I, but I never thought he'd jump again!"
