There's a certain seriousness in the word "teacher". It is uncommon to expect teachers to crack jokes in the classroom. For students, it's a no-brainer that they have to maintain a boundary. And the traditional teacher is often identified as authoritative, respectable, and an enforcer. But some teachers are busting common myths and stereotypes. They are breaking out of the traditional image of how a teacher should be and letting loose. It's a breath of fresh air to see the humorous side of teachers who otherwise would hardly let out a chuckle. 

It is believed that teachers who step back and let their fun side shine have a better influence on students than serious ones. It has a myriad of benefits when a teacher displays a sense of humor. It improves students' engagement as they retain better, and above all, a strong student-teacher relationship develops. A win-win situation. "The use of humor in the college classroom has been researched extensively and has been shown to have many benefits for students," per American Psychological Association.
