So, here's my really long math joke.
There were 3 kingdoms. They had all been fighting over a piece of land that they were all claiming. So, one day they decide that all the fighting is just a waste of time and resources, so they're just going to have one giant battle and whoever is left standing take it. So the first kingdom sends their giant army, with lots of knights and battering rams and siege equipment. The second kingdom also sends their army. They also have lots of knights, but not quite as many as the first. The last kingdom is very poor. They send their lone knight and squire to represent them. When they arrive at the piece of land, they decide that they're going to have a giant feast that night and fight the next morning. So they make a giant feast, and all the knights attend. Meanwhile, the squires have their own miniature feast. The lone squire, however, puts his dinner in a pot, ties a noose with some rope, and hangs it over a fire to cook. The next morning, all of the knights have massive hangovers, and none of them really want to fight. Instead, they decide to send all of the squires in, and whoever is the last man standing, wins. So all the squires start to fight. When the dust finally clears, who should be standing but the lone squire?
And the moral of the story is: The squire of the high pot and noose is equal to the squires of the other two sides.
A groaner, I know.
(If you didn't get it, it's the Pythagorean Theorem.)
