HOOOOO-EEEE! DUCKS ON A POND!
--D-hall, aka detention. Required you to sit in some off-season coach's classroom for I think 30 mins after school. You weren't supposed to do homework or read, just meditate upon your crime.
--Sentences. Assigned in increments of fifty. You'd go to the office, get a slip of paper with the week's sentence on it (usually some sort of moral), and write that on a sheet of looseleaf the required number of times and turn it in at the office.
--Wall sits. The week's group of miscreants (or an ad hoc group, in the moment) would have to put their backs against a wall and scooch down till their thighs were parallel to the floor -- sitting without a chair, basically -- and stay there till whatever insane meathead was in charge told them they could stop. Usually 1-5 minutes in total.
--Licks, aka getting your ass beat with a paddle by some kinky-minded sociopath with rage issues. The number of "licks" depended on the severity of your offense and was stipulated by the teacher or official who sentenced you. The ones who enjoyed performing this duty -- all men, grown-ass adult men, whaling away on teen and preteen boys and girls -- had their own special paddles, with stuff carved into and written on them, and would lovingly caress them in class, name them, use them as pointers, hold them above your head mock-(real)-threateningly, etc.
Dunno if they still do any of this -- for the record, I only ever did sentences or D-hall, although there were plenty of kids who'd choose the licks to get out of writing, say, 200 sentences. Also you could sign a paddle if you got beaten enough times with it. People are crazy.
