Chances are that if an episode title appears on Wikipedia (OR here, before I can revert it and ban whoever is responsible) that involves Nicktoon shows crossing over, it is 100% false

There many reasons why crossovers are rare, even in the same companies, and they usually involve the creators themselves. Say, for instance, a Spongebob/FOP crossover happens, and the question comes up "Which character is more stupid, Cosmo or Patrick?" and the creators can't agree on which character is more stupid (aka, BETTER) so it goes nowhere. Not a good example I know but you at least get where I'm going here, the creators want their characters to look the best, be the best, sound the best, and not be depreciated by a competitor's own characters.

Jimmy/Timmy was an exception, but considering the way JN characters were treated I almost suspect they were bullied into doing it by Nick.
