If you've seen a lot of KOTH episodes, or even one for that matter, you'll realize that most of the subject matter is tongue in cheek. The comedy of the episode is that people are making such a big deal out of such a "harmless" animal. The episode is poking fun at a lot of different things, including negative snake stereotypes, and public hysteria in general. Bobby Hill is generally the most level-headed character (as I see it) and the least opinionated. In the episode, he is the owner of the snake, and is rooting for it the whole time, even while everone else is freaking out. Don't forget that the creator of the show also brought us Office Space and Beavis the Butthead. The episode it seems, in my opinion at least, is more about the ignorance of the general public than the dangerous nature of snakes.
