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 insomniac (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.
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 Krusty Krab 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.

- As of November 1, 2017, The Internet Movie Database (IMDB) gives this episode a rating of 7/10/10 based on 0 ratings by users. TV.com users give this episode a 5.1/10 based on 7 votes.
- The episode's title is a spoof of the word "insomniac."
- The title card scared a few people and younger viewers according to some fans, likely because of its appearance.
- The close-up of SpongeBob's eyes in the title card is used later on in the episode, but crookedly different.
- This close-up was re-used from "New Digs."
- This episode was scheduled to premiere on January 16, 2012, but was delayed due to a plot change. It was originally going to be about Mr. Krabs having a nightmare about turning into a mustard dispenser.
- The mustard dispenser Krabs is still seen in SpongeBob's nightmare, possibly a callback to the original plot.
- This episode was announced at Comic-Con on August 1, 2011 but didn't air until April 9, 2012.
- 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 before.
- The reason for SpongeBob actually getting insomnia might be because he was under pressure to sleep, but said pressure prevented him from sleeping.
- After SpongeBob says, "Yes. SpongeBob SquarePants reporting for sleepy time," he walks into the kitchen, but the sand from Gary's litter box disappears. However, it is a cartoon, so the sand must've gotten erased by the writers when they were writing this episode.
- This episode has some similarities with "A Friendly Game." In that episode, on Hole 2, Patrick wasn't really helping SpongeBob; he was rushing him so he could miss the ball, while in this episode, he isn't helping SpongeBob go to sleep.
- 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.
- This is the third episode where SpongeBob struggles to go to sleep. The first was in "Night Light" and the second was in "New Digs."
- In the Croatian dub, the episode name is "Nesaničar," translating to "Insomniac."
- The Mustard Gauge is a parody of a tire's air pressure gauge.
- Some parts of this episode are similar to the Ren and Stimpy episode "Insomniac Ren."
- 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 turned yellow for a split second.
