I can give you a few examples, but the essay will have to be written by you (all these things happened in our class).
XX students wrote about their teacher when they were writing their essays and ended up writing about her (him) as it.
On April Fool's Day, most of the students arrived at school at six o'clock in order to set up their "teacher's" outfit. But when the teacher came, he was not at all sympathetic to the fruits of his classmates' labor, and was not hit at all.
One of the students could not eat the cherries, so the cherries into the ear, but also sang in tune: "La la la la, I can not hear ~"
The teacher asked us to memorize the "Zhuge Liang Zhuge Liang Zhuge Liang Zhuge Liang Zhuge Liang Zhuge Liang Zhuge Liang", but we all thought that the teacher said We all thought that the teacher said "Zhuge Liang is material Superman" - Superman made of special material!
Military training, because there is no water to drink at night, a student in the dormitory to pour their own water to other students, did not expect to pour into their own bed. When the teacher came, she said that that student had wet the bed, and that the wet spot was especially close to that student's butt!
The teacher told the class to watch a video about insects so they could write their essays. But somehow, the video on insects suddenly stopped and a video of a big Chinese mom doing a square dance appeared!
Just pick a few and use them. If you're not satisfied with any of these examples, you can follow up. If you really don't know how to write, you can still ask. Because I've written a lot of essays like this~
