A blond (who dyed her hair brown) comes up to a sheep herder and says "If I can guess the number of sheep you have, can I pick one out?"  He agrees.  She thinks for a minute and then guesses:
"126!" She was right, and she picked the sheep out and put it in her car.  Then the herder said "If I guess what color your real hair color is, can I have my dog back?"

A blond and a brunette are watching the 11pm News.  The big story is about a man on a ledge of a building, threatening to jump.
Blond:  "Bet ya he won't jump."
Brunette:  "20 bucks?"
Blond:  "Yeah."
The man jumps.  The blond gives the brunette the money. 
Brunette:  "I can't take this.  It was unfair.  I lied.  I saw this on the 6pm news."
Blond:  "Yeah, me too.  I just didn't think he was stupid enough to jump twice."
