Scrooge looks down at the snail and says, What, me have a snail in the house just because it's Christmas? Bah, humbug! And he picks up the snail, drop-kicks it down the garden and slams the door.
Next Christmas Eve the weather is just as bad. Scrooge is again sitting at home when he hears the same noise at the door as last year. He opens it, looks down and there is the snail, who looks up at him and says.....
