One time our prof was reading out loud "The rules of cryptography". One student was dozing off on the last bench. Unfortunately this students roll number was 1.

So this is how this professor usually dictates. He repeats the same sentence 2-3 times. Thus he says "rule number 1" three times.

This student dozing off at the back somehow hears "rule number 1" for the 3rd time and he thinks his roll number is being called out.

He stands up and loudly screams "present sir"

The entire class starts laughing but sir was not amused and the student gets sent to the first bench 😂. This story was pure gold I've told it to so many people lmfao.
