The most naughty thing I have ever done is 100 word composition.

At school, I did many naughty things, but the most naughty one was "helping" my classmates "wet the bed".

There is a classmate named Shi Pukai in our dormitory. Nothing can wake him up when he is sleeping. One summer, at twelve o'clock in the evening, suddenly, there was thunder in the sky, and we were all awakened, but Shi Pukai felt nothing. Look at him sleeping soundly, but at this moment we are all awake and want to play some practical jokes. I poured some water into the cup and fell on his bed.

The next morning, when he woke up, he shouted, "Teacher! I wet the bed. " The life teacher rushed over and took his mattress to the ground in front of the preschool to dry for three days.

It was not until the second semester, when we talked about it again one night, that he realized that it was not he who wet the bed, but we poured water on his mattress. I can't help laughing at the thought of this naughty thing, but I have never done such a naughty thing since then, because it made him lose face and became the laughing stock of his classmates.
