|A blonde girl wants to know what life is like as a brunette girl, so she goes to the hairdresser and has her hair died brown.|
Eager to show the world her newly acquired intelligence, she goes on a walk and meets a shepherd. She walks towards him and says, "If I can guess how many sheep you have in your pack, can I have one?"
"Fair deal," the shepherd says and the blonde guesses '457'.
The shepherd, really surprised about the ability of the girl, says, "A deal is a deal, you guessed the right number, pick a sheep and you can keep it."
After the girl has picked her favourite of the pack, the shepherd says, "If I can guess, which colour your hair had before you dyed it brown, can I get my dog back?"
