Crack an egg at its top or bottom?
The Big-Endians of Blefuscu believed it should be the egg's bottom, but the Lilliputians disagreed, and there was a war.
Should a roll of toilet paper be unwound from its top or bottom?
This is a contentious question but not a causus belli.
I have uttered vociferous interjections more often because there is no roll than because the direction of the unrolling is “wrong”.
It's even worse when there's an egg instead of a roll.
IT'S ABOUT RENEWABLE RESOURCES AND TOILET PAPER!
