One April Fools’ Day when our (not well liked) Headteacher was out on a course, Assembly was led by a senior teacher in a Hall with four points of entry/exit. The classes were delighted when told to file in one door then straight out of another!
The senior teacher had the last laugh, however, when it came to the time to pray. Having requested the usual, “Hands together, eyes closed,” he quietly slipped out of the nearest exit!
That evening there was a governors' meeting at which I amused the attendees by relating this to them, much to the discomfort of the Headteacher. 😉
