A dumb blonde was really tired of being made fun of, so she decided to dye her hair and look like a brunette.
When she had brown hair, she decided to take a drive in the country. After she had been driving for a while, she saw a farmer and a flock of sheep and thought, "Oh! Those sheep are so adorable!" She got out and walked over to the farmer and said, "If I can guess how many sheep you have, can I take one home?"
The farmer, being a bit of a gambler himself, said she could have a try. The blonde looked at the flock and guessed, "157."
The farmer was amazed - she was right! So the blonde picked one and got back into her car. Before she left, the farmer walked up to her and said. "If I can guess the real color of your hair, can I have my dog back?"
