Annoyed with SpongeBob's whistling, Squidward patches up the gap in his teeth. This gives SpongeBob a smooth, cool voice and turns him into a great singer, which Squidward takes advantage of to get the opportunity to perform at a local jazz club.
"Mind the Gap" contains examples of:
- Book Ends: The episode begins and ends with SpongeBob whistling a tune through his gap.
- Bowdlerise: The UK airing of the episode removes the scenes of Squidward screwing SpongeBob's gap closed with a power drill and SpongeBob drinking bubble soap, most likely to prevent children from imitating that said behavior. The screw flying out from between SpongeBob's teeth is edited as well.

- Extra-Long Episode: 12 minutes as opposed to the usual 11.

- Gross-Up Close-Up: When the club owner sees Squidward standing next to CoolBob.
- Head Desk: The club patrons do this in order to create gaps in their own teeth.

- If I Can't Have You…: After getting kicked out of the club, Squidward sneaks back in and is prepared to strike SpongeBob with a mallet while saying, "If I'm not allowed to be cool anymore, then neither is SpongeBob."
- Given a Meaningful Echo when SpongeBob's whistling becomes popular with the club patrons, where Squidward says "You know what, if that is what passes for cool now, then I don't wanna be cool anymore." Followed by Laser-Guided Karma below.
- Laser-Guided Karma: After dismissing SpongeBob and his whistling, Squidward's teeth crack and give him a gap as well- and is forced to pay for the damage caused by SpongeBob when he blew off the roof.
