"Funny Pants" is a SpongeBob SquarePants episode from season 4. In this episode, Squidward grows tired of SpongeBob and his laugher, so he pranks him into thinking he lost his laughter.



SpongeBob constantly laughing, annoying Squidward.

One morning in Bikini Bottom, SpongeBob tells Squidward it's time for work and says "another day, another dollar," but Squidward says, "more like another nickel," which makes SpongeBob laugh uncontrollably. Squidward then goes through a whole day at work with SpongeBob laughing, and even at night. The next day at work, after SpongeBob told the "nickel joke" to the customers, Squidward has decided he has had enough of SpongeBob's incessant laughter. He then sees SpongeBob hurting himself when he laughs, so he tricks him into believing that SpongeBob has a laugh-related illness. According to the made-up disease, if SpongeBob laughs one more time in the next 24 hours, his laugh box will explode, and he will never be able to laugh or giggle again.

For the rest of the day, SpongeBob fights every single urge to chuckle. First, he sees Patrick trip over a banana peel several times and runs away. Next, he sees that whoopee cushions are all over the town. Last, he sees a pie truck in an accident and some of the pie land on some fish. In a drastic measure, he buries himself never to be interrupted by a joke during the night. The next morning, SpongeBob discovers that he has completely lost the ability to laugh. He tells Patrick that he has lost his laugh, but when Patrick looks inside SpongeBob and lights a match, he runs around in circles.

Later, SpongeBob goes to the Krusty Krab to tell Mr. Krabs that he has lost his laugh. Mr. Krabs says that money always makes him laugh, but SpongeBob doesn't feel a tickle. Next, SpongeBob consults Sandy. Sandy gives SpongeBob books about laughter. SpongeBob reads the books, but still doesn't have any effect on his laugh box. Now utterly grief-stricken, all SpongeBob can do is bawl his eyes out, meaning more noise than ever. Feeling guilty, but still wanting peace and quiet, Squidward finally confesses to the sad SpongeBob that he lied to him just so he could get SpongeBob to stop his obnoxious laughing and have some peace and quiet for a while, as his weeping has been more annoying than his giggles, and after Squidward admits everything, SpongeBob laughs to see it has been a good joke and Squidward joins in the laughter. When Squidward says, "You even fell for the thermometer in the boiling oil routine!" SpongeBob immediately stops laughing, saying it's not really funny and goes inside his house. When Squidward laughs too much, he collapses and is taken to the hospital.

Squidward's removed laugh box.

At the hospital, it is revealed that the laugh box actually does exist and Squidward just broke his. Purple Doctorfish points out that one of the others has given him half of their laugh box. It isn't Patrick, Mr. Krabs, or Sandy; it was SpongeBob, who shows the bandage to prove it. Shocked, Squidward starts to laugh like SpongeBob, to his great horror. He and SpongeBob laugh together before Squidward runs out of the building still laughing like SpongeBob in maniac state. SpongeBob then says, "Ah, there he goes off to share his laugh with the world," followed by his own laughter, as the episode ends.

  • This episode was originally going to be named "Unfunny Pants," but was later changed to "Laughbox" when Nickelodeon announced the episode.[citation needed]
  • The title card background for this episode is similar to that of "Squirrel Jokes," except this one is realistically drawn. Coincidentally, both episodes revolve around laughter and jokes.
  • SpongeBob reuses the line "Another day, another dollar" from the episode "Krabby Land."
  • Two clips of SpongeBob laughing in this episode were used in an advertisement for SpongeBob DVDs in 2009.[3]
  • Mr. Krabs is absent when the Krusty Krab closes at the beginning.
  • It should be noted that when Squidward reads the thermometer temperature from the boiling oil as 175 degrees, this is likely in degrees Celsius, which is the metric system. This is because 175 degrees Celsius, which is 347 degrees Fahrenheit, has to be the minimum temperature for cooking oil to not boil, but still be very hot.
  • There is no such thing as a "laughbox" in real-life like the one in this episode. The closest thing to a laughbox is a voice box in real-life.
  • The laughing machine SpongeBob is attached to is similar in appearance to an "iron lung" breathing aid.
  • The sound where SpongeBob tries to laugh, but wheezes instead, is recycled from "Your Shoe's Untied."
  • The fez hat Squidward is wearing when he says SpongeBob became a sad sack was previously seen in "Good Neighbors."
  • When Squidward plays his clarinet after the "Later that same evening" time card, he plays the tune "Mary Had a Little Lamb" as he did in "The Paper," and he still plays it incorrectly.
  • This was the first episode to be written by Luke Brookshier, Tom King, and Steven Banks.
  • This episode premiered separately from its sister episode. This previously happened with "Hooky"/"Mermaid Man and Barnacle Boy II," "Survival of the Idiots"/"Dumped," and "Shanghaied"/"Gary Takes a Bath."
  • This episode marks the second time Squidward's house has grown hands, after "Good Neighbors."
  • This was Todd White's final episode as character designer before he was replaced by Robertryan Cory.
  • This is currently the only episode where both "12th Street Rag" arrangements play.
  • In the Croatian dub, the episode's title is "Smjehuljak" or "Laughter."

  • When Sandy pulls down a chart of the body, her tail disappears for a split second.
