There are jokes about subjunctive mood, give me some! You can write it yourself, but it's funny ~

The teacher asked the students: who has never had a shit in their lives since ancient times, you take the next sentence. Student A: Who defecates without paper? The teacher was very angry and told the students to stand up. At this time, the teacher saw the snow outside the window and said with regret that it didn't rain when it snowed, but it turned into rain when it reached the ground. How troublesome it is to turn into rain. Why didn't it rain at first? The student said: Teachers don't eat shit when they eat, but when they eat it, it becomes shit. How troublesome it is to turn into shit. Why didn't you eat shit in the first place The teacher fainted on the spot.
