Bilingual joke: tough teacher? Answer? Tough? teacher

A school teacher friend of mine hurt his back and had to put a plaster on his upper body. On his first day of school.

His shirt was still wrapped in plaster.

He was assigned to teach the most undisciplined class. Walk confidently into the noisy classroom

He opened the window as much as possible. Just then

A strong wind fluttered his tie. Try to tie a tie.

He picked up a blackboard eraser and nailed a big tack through his tie into his chest.

He had no problem with discipline that semester.

Strict teacher

I have a friend who is a teacher and hurt his back, so he can't wear a plaster mask on his upper body. On the first day of school, he was still wearing a plaster mask. He was assigned to teach the most undisciplined class. He confidently walked into the noisy classroom and opened the window as much as possible. Just then, a strong wind blew away his tie. In order to fix the tie, he picked up the blackboard eraser and smashed a tack on his chest through the tie.

There was no violation of discipline in his class that semester.
