While watching Season 2, episode 8, "The Night of the Bottomless Pit," I noticed that in the opening, cartoon Jim had his hair parted on the right. The next thing I noticed was that live action Jim had his hair parted on the left. Scarcely had I seen this but it was parted on the right. Then it started switching from left to right in the same scene. On the left the hair was flat while on the right it was fluffy. Someone screwed up on this one to the point that it was distracting. Live action Jim seems to have his hair usually parted on the right and fluffy.

The same thing happens in Season 3, episode 12, "The Night of the Legion of Death." Jim's hair starts out flat and parted on the left, then goes to fluffy and parted on the right, then back to flat and parted on the left, during the same sequence of events where he wouldn't have had time to change it. It also changes another couple of times during that episode.

One thing that is ABSOLUTELY CONSISTENT: when Jim's hair is parted on the left, it is flat. When it is parted on the right, it is fluffy. It is very distracting pondering why this is so.

And, AND!!! Artie looked better with his curly hair! Around the time Jim went flat, Artie cut his hair and smoothed it down so it was straight and flat. He looked SO much cuter with curly hair!

It's always fun to look for inconsistencies in a series' episodes. In the old days, we were watching on TVs with poor resolution and we had no way of recording episodes -- so these types of inconsistent looks were much more difficult to catch.

In "The Night of the Legion of Death," Jim's hair starts out flat and parted on the left. In the same sequence of events, when he enters the governor's mansion it is fluffy and parted on the right. When he leaves it is flat and parted on the left. When he escapes in the wagon it is fluffy and parted on the right, and continues to switch throughout the episode at times when he wouldn't have had time to restyle it.

In Season 4, episode 24, "The Night of the Tycoons," in the first scene in the boardroom, Jim's hair is noticeably shorter in a couple of shots than in most of the scene.

In "The Night of the Glowing Corpse," Artie comes out of the bath with his hair wet and plastered down. He has time to put on a robe but not to comb his hair and a moment later, his hair is magically dry and perfectly styled.

In "The Night of the Gruesome Games," when Jim is going down the upstairs hall in the mansion, his hair is parted on the left. A short time later, while searching a room, it is parted on the right. I do believe the shot in the hall is the only instance in the entire series of his hair being parted on the left and fluffy.
