I never really paid attention to this until a few days ago but why were there 2 bed wetting episodes. There was a season 1 episode centering on Arnold's bed wetting then again in season 7 for Sam.

What's that about? Lacking story lines?

I'm glad that I stopped watching this show after season 2. Lazy writing.

Similar stories but different circumstances, in season 1 Arnold was pouring water onto his bed pretending he was bed wetting to get some family attention.

In Sam's case he was actually bed wetting because he was still getting used to moving into a huge penthouse with new family members.
