Dilbert and Dogbert hold tennis rackets. Dogbert says, "Experts say that when you have mastered the mental game, the ball will appear to grow larger." Dilbert holds a tiny ball in his hand. Dilbert replies, "Okay, but I still think these balls are not regulation size." Dogbert says, "Probably just a reflection of your lack of confidence." Dogbert walks away and says, "Three moth balls and a good story are more effective than years of lessons."
