So who is this guy we call 'Santa'

Right so, millions of children worldwide will argue that Santa is a legit figure, agree?

To some, it may be a tale of a jolly overweight paedophile who enters the house of every 'good' boy, providing the boy is a christian (as it is Christmas).

If he were to be real, his reindeers would have to be drugged out on steroids to get to every single house that he needs to ... probably needing to travel faster than light.

                                                   (Or maybe not...)

Another answer about the question 'Mommy, how does Santa deliver all the toys in one night?' is that it is only night time in one side of the world, and daytime at the other... so really he has 2 nights (but still, he'd have to travel at half the speed of light... of course, 149 896 229 metres per SECOND. 

He could just be Chuck Norris' father. 

(Hmmmm)

If he were to exist, he would probably die of mass obesity (As all the snacks left by excited children is eaten by morning.)
