Watch what happens when this 18-year-old kid starts talking about the worst "teacher" he ever had. Chances are you had LITERALLY THE SAME "TEACHER" too. Just FYI, he uses some NSFW words. For a good reason. And yes, it's a metaphorical classroom, not a real one.
Man, remind me to hire this kid. Oh wait, we just did. (Also, he's no longer a kid.)
You may be hesitant to share this thanks to the profanity. Just as a friendly reminder, you could just share it and say, "Hey, there's some profanity in this, but it's so awesome I just had to share it." Totally your call, though.
