The decision by the government to overturn its earlier decision to dispense with the £50 note, has aroused the interest of a group of people who, given the opportunity, might cheerfully overthrow the government.
The Guy Fawkes Society, a group that keeps alive the spirit of the man who, in November 1605, tried to blow up the House of Lords, has said that it can think of no-one more deserving "in all the four corners of the Kingdom" than its hero, the aforementioned, Fawkes to have his portrait on the new note.
But the topic provided an explosive flashpoint when it was raised at Prime Minister's Question Time yesterday. It was like a detonator setting off a bomb, and a violent debate was triggered.
The whole chamber erupted at the mere mention of Fawkes' name, with a cacaphony of screams and shouting as the blazing row raged this way and that, completely out of control, and engulfing all present.
Labour leader, Jeremy Corbyn, usually a picture of calmness, was on fire.
But Pime Minister, Theresa May, who had resisted the flaming war that had gone on for hours, finally blew up and burst forth, saying:
"My government and the British people do not want the face of this man on their money. Despite the fact that this is the £50 note, and most of the lower classes will never see one, I think it wholly inappropriate that we draw attention to someone who was basically a terrorist."
At that point in the proceedings, there was a loud explosion.
