One of the worst jobs in history
"An Arming Squire"
The Knights who fought in medieval times relied on their 'Arming Squires' to provide them with fresh weapons and horses as the day progressed.
During these long battles, Knights didn't bother to take off their armour to go for a toilet break. Instead, they would do their business straight into their armour and spend the day swilling around in the mess. At the end of the fighting, it was the job of the Knight’s 'Arming Squire' to clean his master’s armour of blood, mud – and everything else. There was no easy way of doing this: the biggest lumps of filth were scraped off by hand, and the rest was removed with grass, gravel and sand.
I would have been off sick a lot of the time.
