1. in the episode titled "Eugene goes bad", Arnold, Gerald, and Eugene are sitting on the bed watching a tv show featuring "The Abdicator", Eugene's hero. Notice all of the abdicator merchandise throughout the room.

2. when the scene is on gerald and arnold, look very quickly in the background at the poster of the abdicator on the back wall. In some frames it says "The Abdicator", and moments later it says "The Abdikater". It then goes back to the original spelling.

3. the change from the original spelling goes very quickly, so it would probably be best to record the beginning of the episode in order to see it.
