Class Dismissed

Can anyone identify What this is I have in my right hand? 'It is a pen, Mister Wisdom.' Very good. And with that pen, On a piece of paper. I want each of you to write this: 'If I ever allowed Mister Wisdom, To teach and I would listen. Perhaps he will not consider me, A complete idiot! ' Very good. Now take this to your parents... And return this to me tomorrow! Signed, With a photo of your parents attached! Class dismissed! 'Mister Wisdom... The bell hasn't rung yet! ' Oh... You are going to hear much more than bells, In this classroom! I just want you all to pay attention to the silence! That's the way I like it! And that's the way it is going to be. Unless a fool wants to object to my wishes? Hmmm... Like I said... Class dismissed! And don't forget those photos, Of your breeders! Forgive me children. I meant to say... Unless an 'ignoramous' Wants to object to my wishes! All and 'any' class who forgets That I am the one who dismisses... Will receive many lessons in this room! Tell your parents... Wallet size. No 8 by 10's!
