Sheep

There was once a blonde who was sick and tired of blonde jokes so she died her hair red. she was driving around Derby when she stopped to talk to a shepard. she said “If I can guess how many sheep you have then can I have one?” She thought for a while then said “382”. the shepard said “wow thats correct, you can have any one that you want”. She picked one and put it in her car but before she got into her car the shepard said “If I can guess the real colour of your hair then can I have my dog back?”
