Tricky Master

Many many years ago, in primary school, we were practical jokers. Lee Simian and I stayed back after class to clean the class fish tank. Just as we were about to leave,
I suggested that we play a prank on two classmates. Under the biggest boy in school's desk, we wrote a note that said "Cai Qiming you fat bong" signing off as Lee Yaoqiang, the second biggest boy in class and under Yaoqiang's desk we wrote "stupid blackie" and signed off as Cai Qiming, only to be greeted the next morning to the horror of the two behemoths squaring up to each other just before assembly.
I can still conjure up the image of Cai Qiming slamming Li Yaoqiang into the metal cupboard. The success of the prank didn't give me any pleasure and during the inquest conducted by the teacher, I almost died from fright but no one found out about it but I never played another prank in school afterwards.
