A man is looking to buy some brains. So, naturally he goes to the brain store where he sees a sign on the wall advertising three different kinds of brains : Engineering, Science, and Arts. He asks the clerk behind the counter,"How much for Engineering brains ?"
The clerk replies "$3 an ounce." He ponders this a moment, then asks,"How much for Science brains"
The clerk replies,"$4 an ounce."
Curious, the man asks,"How much for Arts brain?" The clerk replies,"$100 an ounce."
The man shocked ! "Why are Arts brain so much more expensive?" The clerk looks at him like he is from another planet and replies,"Do you know how many Artists it takes to get one ounce of brain?"
