History
Homer asked him for a Monkey's Paw he was selling and he warned Homer that it would bring him misfortune. Homer bought it anyway and then when Marge asked him where he bought it from, Homer thought that his stall had gone, only to realize that he was looking in the wrong place and it was to his left a bit more.
