Been reading nothing but comedy biogs for the last 3 years or so and the current one I have just started is Arthur Lowe's.
Page 10 - a contemporary of his who went to the same school in the early 1920s:-
"There used to be a punishment book, and if you went in it more than once you had to go to the headmaster. I remember a lad being caught smoking in the toilets, and the whole school had to assemble. The lad had to drop his pants and bend over a table. He said 'Let this be a lesson to all of you'."
Read into that what you will.
