SpongeBob's Truth or Square.

It's the Krusty Krab's eleventy-seventh anniversary, and the nostalgia has SpongeBob, Squidward, Patrick, and Mr. Krabs looking back on key events in their lives. Right before the party begins, however, they all get locked in the freezer! With a hungry crowd and Plankton ready to steal the formula, they race through the air ducts to find a way out. Meanwhile, Patchy goes to Nickelodeon Studios to cast a star-studded 10th anniversary special. When the big event airs, however, he finds the guest of honor didn't show up...SpongeBob himself.
