only says yes no matter what, infact he is physically incapable of saying other words and can only say "yes", like bro he is physically incapable of saying "no, negative, yesn't, ok, maybe, eh" infact he CANNOT SAY ANY OTHER WORD THAN YES, so yeah he can only say yes. ALSO if he says anything else, he will explode spontaneously and instantly die, if that doesn't happen 20000 nukes will be sent to his location, and if the nukes don't hit, the radiation from the nukes will go to him and kill him.
