class names

Hey in school am now having a bet with my history teacher and if can say his name correctly I can call him Kelly for the whole year, or day which I forgot. All I need to do is not say it incorrectly and it is going to be difficult for me since am to used to calling him what I call. I say history is a fun class to be since you can know the truth in history like the evil things Columbus did to the Indians. The hardest class I have to say is my Japanese class because we have a test every friday.
