065b - Funny Pants

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 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 to never 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 cry his eyes out, meaning more noise than ever. Feeling guilty but still wanting peace and quiet, Squidward finally confesses to the sad SpongeBob, as the weeping has been more annoying than SpongeBob's 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, and goes inside his house. When Squidward laughs too much, he is taken to the hospital.

Later, it is revealed that Squidward has lost his laugh and Purple Doctorfish points out that someone has given him half of their laugh box. It isn't Patrick, Sandy or Mr. Krabs; it was SpongeBob. Squidward starts to laugh like SpongeBob and runs out of the building. SpongeBob then says "Ah, there he goes off to share his laugh with the world," followed by his laughter.
