A red-head was walking down a country road one day and came across a penned-in field with sheep in it. Getting the attention of the shepherd, she asked him if she could have one of his lambs if she could guess how many were in the pen.
"Sure," he said, adding "it's gonna be a mighty hard, but go ahead."
"Hmm, she pondered." Then she suddenly said, "175."
"My gosh," said the shepherd, astounded. "How'd you do that?"
"Just a lucky guess," replied the red-head.
"Well, deal's a deal." And he handed her a lamb.
As she was walking away, the shepherd called behind her, "hey, if I can guess your original hair color, can I have the lamb back?"
"I guess," she responded, "but that's gonna be pretty hard, too."
"Well, I'll try just the same." He thought a minute and then said, "I'd say your original hair color was blonde."
"How in the world did you guess that?" she asked.
"Just a lucky guess. Can I have my dog back?"
