World Teachers' Day is celebrated on October 5th and serves as a day for us to show gratitude toward educators and all of the contributions that they've made in our lives. It was first established in 1994 by UNESCO, but the theme for this year is "Young Teachers: The Future of the Profession" in hopes of bringing attention to the challenges that young teachers face.

Teaching is often a very stressful, and sometimes thankless job. In fact, recent survey found that nearly half of all teachers found their jobs to be extremely stressful.

In some cases, teaching can be so stressful that even one of the world's most renowned badasses wasn't up for the job. Before he was famous, Liam Neeson tried to go into teaching and called it "probably the most difficult job I'd ever tried to master." He quit after punching a 15 year old who pulled a knife on him. Neeson discusses the incident at about two minutes into this 2012 interview:

He tells the story of an incident which happened while he was training to be a teacher. Neeson claims that a "big" 15 year old was being disruptive. After asking him to leave the classroom, the student responded by pulling a knife on him.

"I had to punch him and then I was reprimanded for hitting the kid." claimed Neeson.

So there you have it, teachers of the world. You're doing a job that even Liam Neeson couldn't handle, and I'd say that gives you permission to go in and get trashed in the teacher's lounge on this blessed day. Happy World Teachers' Day!
