I was told to write 500 [such] lines at school for talking in class. I thought that was ridiculous and said so. The teacher immediately ordered me to do an extra 500, at which point I burst out laughing. He ran over to me, and screamed in my face to make that 1,500 lines and I had better not laugh again if I knew what was good for me!
I Sellotaped 5 pens in a row so I effectively only wrote 300 lines, but it still took me ages.
