I've heard that the confirmation hearings to become a Supreme Court judge are a cakewalk compared to the examination procedures for becoming a Mighty Mod.
Apparently the Inquisitors, led by the Grand High Inquisitor subject the applicant to a fearsome questioning.
A chap might be asked, which of the seven nations in Classic Diplomacy has their favourite colour, and if a chap says "France, no England" he's thrown into the bottomless pit.
He must also know how to convoy an army through the the eye of a needle to capture the Promised Land.
Or explain the fabled Unwritten Rule and it's applications
The Inquisitors also question the applicant's moral character.
If they find out that when the chap was a young man he neglected his studies of the writings of Clausewitz, or Sun Tzu, or Liddell & Hart to gaze adoringly at a poster of Wonder Woman, or Barbara Eden in her I dream of Jeannie costume then it's the bottomless pit.
There's also the hen and a half question
If a hen and a half lays an egg and a half in a day and a half, and your single hen lays eggs at the same rate, then how many eggs do you have at the end of a week ?
Of course all this is anecdotal and not corroborated, but I hear these whispered tales when I'm about and around, as I say 'tis all shrouded in mystery. As it should be.
