Joke: The apple painted by the teacher _ laughs till my stomach hurts _ laughs till my girlfriend is happy.

A young female teacher gave her second-grade students the first lesson. In order to leave a good impression on the students, she drew an apple on the blackboard and asked the students back, "What is this?" The student replied: "* * *" She was so angry that she went to the headmaster in tears. The headmaster came to the class and taught the students, "Are you asking you to bully the teacher?" Looking back at the blackboard, he flew into a rage and said, "Good! You not only bullied the teacher, but also drew a * * * on the blackboard! " ?
