a blonde, getting tired of all the blonde jokes, dyed her hair brown.
She was driving in the country one day, when she saw a farmer in the field with his sheep, and pulled over to talk to him.
She gets out of her car, and asks the farmer, "If I can tell you the amount of sheep you have, may I take one home?"
The farmer aggrees, and she says,"427"
The farmer is amazed, so he tells her to pick her sheep.
She gets one, and puts it in her car, when the farmers says to her, "If I can guess your true hair color, can I have my sheep dog back?"
