A blond girl gets sick of being called stupid, so she does something about it. She dies her hair a really dark brown. Then she thinks to herself, "Now I need someone that i can prove to that I am smart." So, she finds a sheep farmer and asks him, "If I can tell you how many sheep you have on your farm, will you give me one?"
The farmer says, "Sure, there's no way you can guess that."
So, the girl thinks a while, then says, "You have 356 sheep on your farm."
"That's amazing!" the farmer says, "how could you possibly know that?"
"Us intelligent people just know these things." Then she takes her sheep and starts to load it in her car, when the farmer walks over to her.
"Ma'am, if i can tell you your real hair color, will you give me my dog back?"
