Well the thing about the Hank Scorpio episode is if the wackiness of it had been contained in just that episode, it wouldn't be a big deal. The problem is like Ian says, the Hank Scorpio episode pretty much ended up being a sign of things to come. Even though I still like the episode, when I look back on it, the episode is the first major sign that the writers were starting to run out of idea's and as a result, started taking the series from a family sitcom with some crazy cartoon elements, into a crazy cartoon with some family sitcom elements.
