There was a blonde who was tired of all the blonde jokes going around and decided to dye her hair brown. She then went for a drive in the country and came upon a shepherd herding his sheep across the road.
"Hey, shepherd! If I guess how many sheep there are here, can I keep one?" The shepherd is puzzled but agrees. Out of the blue, she blurts out "352!" He is stunned but keeps his word and allows her to pick out a sheep. She picks out the cutest one.

He looks at her and says "If I guess what color your hair really is, can I have my dog back?"
