In Krabbyland, when Mr. Krabs holds up the sign right before unveiling the park, he says "Krabbyland: where a kid can have fun!" If you watch his mouth as he says this, you can clearly see that he is mouthing 'Where a kid can be a kid,' the slogan for Chuck E. Cheese. Whether this overdub was intended as a joke or not is unknown.
SpongeBob says "who knew this guy" 15 times.
The Camping Episode was featured in a episode of Family Guy titled Road To Rupert.
While learning the German version of the Campfire Song Song, Santiago Ziesmer was staggered by the speed and accuracy required to sing it. "I can't do this", he thought, "I can never do this." He and the crew considered whether to pitch it higher, so they had Ziesmer sing it slower and then speed up his voice. But it sounded wrong so they couldn't use it. So Ziesmer practiced and practiced the song until he got it right, despite getting tangled up a few times in the beginning.
