I would stab you in your weak underbelly (for someone whose name is taken from LOTR, GandalftheGrey666, you know very little about the books; it's the underbelly, not the head).
*Pokemon battle theme* I choose you, Knight! Use Shield Bash! *It's not that effective...* Use Sword Slash! *It's super effective!* Finish him off and use Self Destruct! *BOOM* S***!
I kick you so you fell on the floor, then i remove the helmet and give you a knock-out-punch in the face, after that i strip you and bring you out, throw you in the trashcan... but ill retain the armour, nice room-decoration.
