It would be a damn short discussion given that a prime number is defined as an integer that has no integral factors but itself and 1. Ah I do enjoy maths it leaves no room for airy fairy nonsense.
Prime numbers are the irreduceable factors which multiply to make compound (i.e. non-prime) numbers. End of discussion. Therefore the armadillo will explode.
As it was such a silly question in the first place, and as everybody already knows that 2 is a prime number without needing to discuss it, I don't want any of your stupid stars.
