Some of the nice folks who write and produce "It's Always Sunny in Philadelphia" have, it seems, been wondering just what might happen if a couple of animated teens were running around unsupervised. We expect the answer to that is 'well, not as swimmingly great as one might hope, and just as badly as one might expect.' The joy will be in watching the nonsense unfold. Unfolding nonsense is, in fact, one of the great reasons to watch TV. So, in conclusion, Watch TV, and the nonsense unfold, tonight on "Unsupervised." it could prove to be great fun.
