Once there was a blonde driving home from work when she saw a sheep farm. She stops and asks the farmer if she can have a sheep. The farmer says "If you can count all my sheep I�ll let you have any one you want."
The blonde looks around her for a moment and says, "You have 356 sheep."
The farmer exclaims, "Wow -- you�re exactly right. I guess blondes really aren�t dumb. Now go pick yourself out a sheep."
The blonde makes her choice, picks it up, comes back to the farmer to thank him.
"Oh no," he says, "you can�t have that one."
"Why not?" asks the blonde, "you said I could have any sheep I wanted."
And the farmer replies, "Ma�am, that�s my dog."
