Liam Neeson is best known as a man with a particular set of skills, but I bet you didn't know it included punching teenagers.
A Redditor dug up an interview Neeson did a few years ago where the actor revealed while working as a teacher, he punched one of his students.
However, Neeson did have just cause to perform the violent action: The kid pulled out a knife. Although Neeson acted in self-defense, he was fired from his job.
It seems like Neeson was a badass even before he starred in the "Taken" films.
You can check out Neeson's take on the situation in the clip below, around the 2:25 mark.
