But seriously, if you're 読書 it for the first time, あなた should put an actual effort into keeping an open mind and done read it with the mindset that あなた need to find something to insult.
If あなた think they'll find it funny? Go ahead. I had to do the same just to get through the thing without throwing my kindle against the ウォール in frustration. If it's to insult them, then no. Leave it out, even if it's just good-natured ribbing; no need to stir trouble for the sake of it. I don't know あなた または your friend, so its up to you; just giving my thoughts.
