How does old, fat Father Christmas deliever all our prezzies in one night?
Does he have a magic sleigh that goes fast?
Does he stop time at midnight?
Does he infact not deliver himself but hires elves/posties/Ernest to do it?
In my opinion (after watching The Matrix a few too many times) Santa discovered the truth about our world and can bend the rules and fly/kung-fu/stop bullets/bend spoons and deliver presents in bullet-time
