Once there was a blonde who was tired of hearing blonde jokes, so she died her hair brown.
A few days later she was driving in the countryside and stopped to let a flock of sheep pass. Admiring the cute wooly creatures, she said to the shephard "if I can guess how many sheep you have, can I take one?" The shephard, always being a gentleman, said "Sure!"
The blonde thought for a minute and for no discernable reason said "352." This being the correct answer, the shephard was amazed, and exclaimed, "You're right! OK I'll keep my end of the bargain. Take your pick of my flock."
The blonde considered the flock and finally picked one that was by far cuter and more playful than any of the others.
When she was done, the shephard turned to her and said, "OK, I have a proposition for you. If I can guess your true hair color, can I have my dog back?"
