Room 101 poll answear please?

Ok so room 101 a room where you can banish anything forever. Our rules: You can't banish a student or teacher and I need to persuade my cl to banish it too. I don't want homework because loads of people have done it, I want something interesting.It can be 2 or 3 things and the speech is around 2 minutes. Can you give me some ideas please.
