"Fifty Few" & Other Punishments

The famous punishment dished out by Mr Petherbridge
"Few things are more distressing to a well adjusted mind, than to see a boy, who ought to know better, disporting himself at improper moments"

Jon Bratton writes
In my time it was a "well regulated mind" rather than "well adjusted mind" but no matter. Did anyone ever get a "hundred few"?
What's more, the question needs to be asked, did anyone have to write out
"Few things are more distressing to a well adjusted mind, than to see a girl, who ought to know better, disporting herself at improper moments"

On that subject, Angela Elliott writes
Miss Wood who became Mrs Evans sussed that I had lines, ready to complete, starting 'I must not' and she gave me a couple of hundred starting 'In future'. She was my favourite teacher until then!
