OK, class, quiz time: Who lives in a pineapple under the sea? No takers? OK, here's a hint: Absorbent and yellow and porous is he!

You may still be stumped, but trust me, show this to anyone under the age of 11 and they'll be screaming the answer at you: SpongeBob SquarePants!

"SpongeBob," the wackiest, wildest cartoon on the Nickelodeon channel, was created in 1999 by marine biologist-turned-animator Stephen Hillenburg. The show has seen four successful seasons on Nickelodeon, charming the kids with its hyperactive, flush-the-Ritalin attitude, but also making fans of many parents as well, who can appreciate the series' absurd, over-the-top vibe.
