The Chronicles of Narnia: The Lion, the Witch and the Wardrobe
Fifteen years later they find the wardrobe and return to England, becoming children again. The professor enters the room and asks what they were doing. Peter replies, "You wouldn't believe us if we told you, sir." The professor tosses him the ball that broke the window and replies, "Try me." Lucy later goes to the wardrobe because she wants to return to Narnia, but the Professor tells her he has been trying for years, and that the wardrobe will probably not work again.
