A Grumpy Christmas is a magazine story.
Although Christmas is a merry time for everyone, George the Steamroller lacks in the festive spirit and rather being cheery, causes misery for everyone much to Thomas's dismay. George flattens several snowmen beside the roads, and cracking icy roads that children are sliding on, George just laughs and puts on a nasty grin.
However, he soon gets his comeuppance when the ice on a frozen pond breaks under his weight and he falls into the freezing water. George has to stay in the pond whilst children make a snow driver in his cab. Now both Thomas and the children have the last laugh.
