Quote: "What, there's some deep philosophical statement implied in Spongebob Squarepants?"
Yeah, why not
Patrick is supposed to represent Aristotle and Spongebob comes from one of Aquinas' theories of Natural Law and Bikini Bottom is entirely based on Plato's analogy of the cave...
No, what I mean with understanding is, that people think of Spongebob in the wrong way, some childish kids TV program, but then I guess the humour generally applies to people's personality, like The Office.
Quote: "I think it's just a pop culture fad, although I can't work out why that is."
I disagree, I genuinnely enjoy it, its funny and entertaining, so I watch it and people I know who like Spongebob, do like it, not because everyone else does, because they don't, its a Marmite situation, you either love it or hate it. But you do get it as a fad in pop culture, but that doesn't stop me from loving it.
