Crossword joke 200 words

We have a female math teacher from Sichuan, and her Mandarin is OK, but "pro" and "question" are always confused.

Once she finished a question for us and asked everyone, "Do you understand? If you don't understand, you can get up and kiss me. " The students were all surprised when they heard it. Everybody look at me, I look at you. Nobody got up. She added, "Why, I'm embarrassed to get up and kiss, aren't I?" The students were even more disgusted, and some almost laughed. Seeing that no one asked, the teacher said, "I am too old to kiss." Well, I won't come to my office after class and' kiss' me when no one is around. " Ha ha! The students finally couldn't help laughing.
