I'm sure there's some copyright violation, but you're not doing it for profit, so you're really doing some free advertising, right?

And who said Spongebob's for kids? That's my favorite show, although I wouldn't encourage my kids to watch it (a little irreverent and pessemistic - who wants kids to be that way?)

Best line from Spongebob "Don't worry Captain, we can buff out those scratches!" (after boat destroyed by backing into rocks)
