The Brunette And The Sheep

Once there was this brunette who was driving her corvette with the wind in her hair.

She looked and she saw a farmer with a flock of sheep so she drove over and asked the farmer:

- if I can guess how many sheep in you're flock will you give me a sheep.

The farmer says:

- OK.

The brunette says:

- 485.

The farmer says:

- that's right but if I can guess you're natural hair color can I have my sheep back.

The brunette says:

- OK.

The farmer says:

- blonde.

The brunette says how did you know.

The farmer says you just picked the dog.
