I remember a long time ago, in grade like 3-4, some special needs kid bit my face. Like, not just like a normal bite that you would imagine on someone's like arm or something, but like my face bled. I beat the fuck out of the kid because it was one of the only things that came to my mind. I broke the kids glasses. I ended up getting in way more trouble than he did.
Don't fuck with retards, they have grownups on their side.
