The Big Question.

So let's get right to it - how does Santa Claus get round all the houses to deliver the presents in one night?    Can't be done- right?  Yet it happens.  So - ideas?  Well, there's the Artemis Fowl solution - Santa Claus is actually an elf called San D'Klaus and as everybody knows, elves can stop time, so it actually takes as long as it takes, but for us humans time stops so it appears to happen in the space of one night.  Then there's the parallel universes theory - that there are an infinite number of Santas in an infinite numbers of universes, each delivering just a few presents to just a few houses - easy-peasy.  And my personal theory - Santa is a quantum entity.  Quantum theory says that if that were so, Santa would be able to be everywhere all at the same time, which again makes the apparently impossible simple.  What do you think?  Of course you could stay up tonight and try to catch him at it - but then, as we all know, if you don't go to sleep, he won't come!
