It is a fine day in Bikini Bottom, and down at the Krusty Krab, SpongeBob adds one percent too much mustard to the Krabby Patties. Mr. Krabs isn't happy with this, as this gross excess would lead him to bankruptcy within the next four hundred years, however, he assumes SpongeBob is an insomnia (a disorder where a person has sleeping difficulties), so he sends him home to get some shut-eye.
SpongeBob has a hard time sleeping, so he goes to Patrick's house. Patrick tries to help SpongeBob asleep by reading a bedtime story. This doesn't work, since it is a "wake-up story" (The Land of Perpetual Excitement). Then, Patrick sings SpongeBob his "lullaby," but it is really a wake-up song, since it has the lyrics "Get up, be active! Get up, be active!" Then Patrick gives SpongeBob some coffee, which makes him even more awake.
After realizing he drank coffee, SpongeBob starts running around and hallucinating things, such as a talking glass of milk, a bunch of Squidwards, etc. Then he hallucinates Patrick eating him, thinking he's a sponge cake. Inside Patrick, SpongeBob hallucinates a sunrise. He begs it to let him sleep for just five minutes before he hallucinates Sir Cecil the sleep wizard. Sir Cecil puts sleepy dust (which is really litter from Gary's litter box) on SpongeBob, then he falls asleep. When SpongeBob wakes up in Gary's litter box, he snaps back to reality.
Realizing he's late for work, a very tired SpongeBob goes to the Krusty Krab, only to sleep in a barrel of mustard. Mr. Krabs takes him out of the barrel of ruined mustard, and wonders why he couldn't sleep. SpongeBob confesses that his "insomnia" got the best of him. Then, he starts crying tears made of mustard. He cries the perfect amount that is needed to be on the patties. Squidward is happy and claims that it's the best day of work ever, because he got to see SpongeBob being forced to cry mustard.

- The close-up of SpongeBob's eyes in the title card is used later on in the episode, but crookedly different.
- This close-up is similar to the one in "New Digs."
- This episode was first announced at the SpongeBob panel at Comic-Con on August 1, 2011. At the panel, several crew members discussed the dream sequence in which Mr. Krabs' eyes turn into mustard dispensers.
- Although this episode premiered in 2012, it was made in 2011 according to the credits.
- This episode marks the fourth instance in which SpongeBob appears in the title card. The first was "What Ever Happened to SpongeBob?," the second was "Oral Report," and the third was "Restraining SpongeBob."
- SpongeBob was deprived of sleep before in "Fear of a Krabby Patty." His sleep deprivation once again led to hallucinations. Both hallucinations also had to do with work. He was also deprived of sleep in "I ♥ Dancing," where Squidward forces him to dance until he collapses, and in "Squid Baby," where Squidward's constant crying prevents him from sleeping for several days.
- This episode's plot is similar to "Squidward in Clarinetland." Both SpongeBob and Squidward get lost in a new land. Then they both come out of it, realizing it was a dream.
- Although, Squidward experienced it in the locker, while SpongeBob experienced it from insomnia.
- Mr. Krabs had not reacted before over SpongeBob flipping the patties a different way.
- This episode premiered on Dennis Quaid's 58th birthday.
- This episode premiered on March 24, 2013 in the British Isles after the local Kids' Choice Awards.
- This episode premiered in the British Isles three years after "Squidward in Clarinetland" premiered.
- In the Croatian dub, the episode name is "Nesaničar," translating to "Insomniac."
- This episode premiered in the "Two Whole Weeks of Never Before Seen SpongeBob" event.
- The episode's title is a pun on the word "insomniac."
- The mustard gauge is a parody of a tire's air pressure gauge.
- After SpongeBob says, "Yes. SpongeBob SquarePants reporting for sleepy time," he walks into the kitchen, but the sand from Gary's litter box disappears.
- When SpongeBob runs to Patrick's house, Squidward's house is missing. The same error occurred in "The Secret Box" and "Missing Identity."
- When SpongeBob enters the Krusty Krab, Squidward is missing from the register.
- When Mr. Krabs calculates and gets 411, he is adding numbers that made a much higher number. The real answer is 511.
- When SpongeBob is in his house, he still has his night clothes on, but when he exits his door, he has his regular clothes on.
- Closed Caption error: When SpongeBob reacts to the severe toe barnacles, he says "Bleah!," but the captions display it as "(screams)."
- When SpongeBob was pushed out of the Krusty Krab, his left eye turns yellow for a split second and his eyelashes appear to be missing.
- Mr. Krabs should have known that he would be dead before 411 years have passed since his birthday is November 30, 1942 and 411 years would be a long time.
