This happened with one of my friends when she was in her first year. As we all know it is quite compulsory for every student to sign the register in order to get attendance every day and this regularly happens outside the mess before students enter to have dinner. 

It happened on that important day when my friend was tired of signing every day and she chose to sign for the whole month on the same day. However, the majority of it was compelled by the fact that the register isn't checked thoroughly but on that particular day, the superintendent checked the register and complained further. Eventually, the DSW's office inflicted a black dot to serve as a warning to other students. The above incident has caused many laughing riots on several occasions.
