Okay this is everyone's dream: you go to a garage sale and in the stack of $1 pictures is a Rembrandt worth millions? Would you pay the dollar, take the painting, without saying a word to the seller? Or would you say to them, "look, you don't know it but this painting does not belong in this stack of $1 pictures because...."

What would you do? Pay the buck and run, or be the seller's eternal hero?
