My friend Tyrone acts up in class?

Well, you see, my bestest friend Tyrone acts up in class all the time. In Art class, he goes ballistic when people ask him to to make stick figures for him because they don't know how to. He acts up in Math class when our slutty teacher asked him what 2 plus 2 was. He is one irritated dude. In the hall ways he starts screaming and starts masturbating on the ground. Is he mental or something?
