My sister is in year 11 and today all the year 11 girls have an after school detention for wearing too much make-up. ALL OF THEM! How I laughed when my mum told me.
I forgot my English notebook, got a detention, then found it in my bag later. I had to write "I am an idiot" on one side of A4 as punishment. Took two minutes. Easiest two minutes of detention I ever did.
