A man decides to get a job as a teacher at a primary school. On his first day, he walks into the classroom and starts to introduce himself to the students.
He says, "Hello, my name is Mr. Smith, and I'm going to be your new teacher. I'm very excited to be here and can't wait to start teaching you all."
One student raises his hand and asks, "Mr. Smith, are you married?"
The teacher responds, "No, I'm not married. Why do you ask?"
The student says, "Well, if you were married, you would understand that sometimes it's like managing a classroom full of children."
The entire class erupts into laughter, including Mr. Smith. He realizes that he's going to have a fun and interesting year ahead of him with this group of students.
