Once upon a time in Northern Ireland, there lived a young man called William. When he was 19, he enrolled in a Physics and Computer Science course at Belfast University. While he had the skillset and intelligence to complete the course, he dropped out shortly afterwards, having decided that it wasn't the path for him. Having left university, he returned to his home town, a few miles north of Belfast, and got a job working as a forklift and truck driver for Guinness Beer. However, he yet again decided that this path wasn't for him, and so he decides to follow two of his older siblings into teaching, taking a four-year course.
In his second year, as part of his course, he was instructed to teach a class of 14/15/16-year-olds. Times don't change, and even when he was on this course in the 1970s, trainee teachers were treated like substitute teachers and nobody would take them seriously. This happened with William. When the students saw that they had a different teacher, they paid him no attention, and carried on chatting when he asked them to be seated and listen. Seeing that these attempts were futile, he raised himself up to his full height, about 6'4", and barked at them to sit down and listen at the top of his lungs. Everyone did. Apart from 1 15-year-old boy. William asked him to sit down again. Again did the boy not listen. William approached the boy, leant down and told him to go outside and that he shall be dealt with shortly. Returning to the front of the class, William expected the boy to follow his instructions, but when he turned, the boy had not budged. So William yet again walked up to the boy and yelled at him to go outside, to which the boy pulled out a knife. By this point, William was furious, and so he raised his arm and gave the boy a good whack in the head, which sent him flying across the room, narrowly missing some other students. The rest of the class were well behaved after that (can't begin to think what may have prompted the sudden change in attitude).
After his superiors found out that he had almost knocked a child unconscious, no matter how deserving of it said child was, William was expelled from his course. Now, with nowhere to go, he turned to summat that he really wanted to do, but didn't have the opportunity to chase until this point: acting. He spent a few years on the stages of Belfast before being discovered by a Hollywood director and made a Star.
That man was, and indeed still is, William John Neeson, who appeared in Star Wars Episode I: The Phantom Menace as Qui-Gon Jinn.
