Ridiculus Debate of the century!

[blackmage_nuke]

Let us say theoretically you have a perfect sphere and you are using it as a dice, would it be a D1 or a D∞?

Ie:
If you were to use a sphere as a dice would you consider it a one sided dice (always rolls the number 1) or an infinite sided dice (can roll any positive integer)

Suggested arguements:
A D∞ is impossible
A D1 is useless
