Exactly. If you can't beat them with force then beat them with smarts.
Also lol at the pencil stabbing, only place I ever stabbed someone with a sharp pencil was their hand onto a desk. If I remember correctly they were fucking around and taking my stuff, so I went ahead and stabbed their hand the next time it arrived on my desk to snatch something. The teacher saw the whole thing and just looked at me and said "was that really necessary!?" and I just stared at them with a straight face and replied "yes" as I was withdrawing my pencil. Quite glad I didn't get in trouble for that one.
But yea, I've never gone for the jugular, lol. Worst I ever did was smash someone's head into a bunch of metal bars.
