The blonde and the rancher

A blonde dyed her hair black, and thought she looked so great she decided to go for a drive in the country to celebrate.

After a bit, she was driving by a sheep ranch and stopped to look at the sheep which she liked very much.

She went over the the rancher and said, "If I can tell you how many are in this field right now, will you let me have one?" The rancher said, "If you can count that fast, sure!"

The blonde said: "524." The rancher, amazed, told her to take her pick, for that was the exact count. After a few minutes, the blonde came back with her animal.

The rancher said, "If I can tell you what color your hair was before you dyed it, could I have my dog back?"
