SpongeBob's Truth or Square (also known as Stuck in the Freezer) is a 2009 made-for-television comedy television film and an hour-long episode of the American animated television series SpongeBob SquarePants that was produced as the 123rd and 124th episodes of the series. The special originally aired on Nickelodeon in the United States on November 6, 2009, celebrating the tenth anniversary of the television series. This is the second SpongeBob SquarePants television film, following SpongeBob's Atlantis SquarePantis. Its animation was directed by supervising director Alan Smart, Andrew Overtoom and Tom Yasumi.

In the special, SpongeBob and his friends are accidentally locked inside the Krusty Krab on the day of its "Eleventy-Seventh" anniversary celebration. As they crawl through the ventilation system trying to escape, they look back on shared memories through flashback moments. Meanwhile, Patchy the Pirate is holding a TV Extravaganza, and is waiting for SpongeBob to show up to it, but with no reply, Patchy sets out to Bikini Bottom in a fit of rage.

Truth or Square was written by Luke Brookshier, Nate Cash, Steven Banks, and Paul Tibbitt. Guest stars include Rosario Dawson, Eddie Deezen, Triumph the Insult Comic Dog, LeBron James, Tina Fey, Will Ferrell, Craig Ferguson, Robin Williams, and P!nk, with Ricky Gervais having an uncredited voice cameo as the narrator. Upon release, the special attracted an estimated 7.7 million viewers, but was met with mixed reviews from critics; although some generally spoke positively of the special's main animated segments, most criticized the Patchy the Pirate segments, which were described as unfunny and filler.
