Matematikskämt!

Applied Optics: The temperature of Heaven can be rather accurately computed. Our authority is Isaiah 30:26, 'Moreover, the light of the Moon shall be as the light of the Sun and the light of the Sun shall be sevenfold, as the light of seven days.' Thus Heaven receives from the Moon as much radiation as we from the Sun, and in addition 49 times as much as the Earth from the Sun, 50 times in all. Using the Stefan-Boltzmann law for radiation, (H/E)4 = 50, where E is the absolute temperature of the earth, gives H as 525 C. The exact temperature of Hell cannot be computed.... [However] Revelation 21:8 says 'But the fearful, and unbelieving...shall have their part in the lake which burneth with fire and brimstone.' A lake of molten brimstone must be at or below [its] boiling [temperature], 444.6 C. We have, then, that Heaven, at 525 C, is hotter than Hell at, 445 C.

Because all the Poles are in Eastern Europe.

Och så följdskämtet:
Well actually there are Poles in Western Europe but they're removable.
