Never thought I'd read: Santa need not be that fat in all dimensions...

The only difference in dimensions at speed is the distance between the uppermost height and the lowermost height of the part of the flue he occupies at any instant. Same problem with the gift. If it fits down the flue at any speed, it fits through a doorway. | |

To fit in a chimney would require Santa to contract in two dimensions, both of which are perpendicular to the direction one would have to travel to get up or down the chimney. | |
