"If I had known you were only going that far,mallethead, I would have stayed in,"Amy told her friend Jim,after he fell out of the cardboard box and lost his pompom snowhat,due to his
big mallethead,as he tried to boxslide downhill by himself. Down below,at the
bottom of the snowy hill,Pat and Gary,wearing plain snowhats and overcoats,thought,"What a malletheadJim is, partly for wearing a pompom snowhat,and a jacket! Plain snowhats and overcoats are the ideal

hat, since his head is a mallethead and he is a mallet head!"
