Zombie

Don't bother looking at the school I went to- those kids from writing class were full of nothing but hot air (well, to be fair, that particular class was normally taken by 9th graders, so I was surrounded by kids who were 3 grades lower than me).

...Wait, actually, on second thought, DO bother looking for brains there! Don't pay any attention to me, just go right to the school and chomp on the heads of two boys who are both named Josh! Forget that you ever saw me, Mr. Zombie sir! It's like I wasn't even heeeere...
