Mike Cramp, better known as "MC", is the cool new teacher at Lakewood Elementary School. He was going to be a new 4th grade teacher and Mr. Ratburn's class wanted to have him. But, he decided that he liked teaching 3rd grade better when Arthur's class realized they wanted Mr. Ratburn again as a teacher. He will teach 3rd grade during the upcoming school year in Mr. Ratburn's current classroom.
