Bender is in the gym playing basketball and Mr. Vernon comes in and asks him what he is doing. After he kicks the ball at Mr. Vernon his left shoe falls off. As they leave the gym his shoe is off and left in the gym, but yet when Bender and Vernon both come back into the library with all the others, he now has his shoe back on. This time it is two black shoes, but before one was a black and one was a white shoe.
