If you take a moment to watch an entire episode of Sponge Bob Squarepants, you will discover that it's is a brilliantly crafted show. For one, it layers humor for three target age-groups. Kids love it, but it's also full of sexual innuendo for their parents. And like all shows in the Nickelodeon tradition, it seems to be written primarily for stoned young men aged 12 to 25.
