The Jerkass

''I'm gonna litter these LEGO bricks on the floor! Then everyone without shoes'll step on 'em, and it's gonna hurt A LOT! WAAAA HA HA HA HAAAAAA!''

The one who thinks doing small annoying things, like putting gum under the table, is Pure Evil when, in actuality, he just looks dumb to everybody. Most likely some stupid little boy who's trying too hard to be cool or hated by people, but The Jerkass could take form of an adult who does the same thing.
