He is a math teacher at Diknoz Highschool. He claims that math is everyone's favorite subject. Everyone didn't feel like answering 5-7=?. One person in the class said "pen!s". He quickly went from happy to angry. Jeffy even threw a Box of Cheerios at him. It hit him right in the face.
He may seem friendly for a second, but he's actually an extremely rude and horrible teacher. He wants things his way or loses his stuff. He also doesn't care and will swear to the class.
