Dilbert pushes a shopping cart through a grocery store. A clerk says, "Hold it right there, fella!" Dilbert turns around and says, "Uh-oh . . . You must have seen me eat that grape in aisle 'B.'" The clerk responds, "I just want to make sure you pay for it." Dilbert lies on the scale at the cash register. The clerk says, "Looks like 192 pounds. What were you before you came in?" Dilbert replies, "Happy."
