Slapstick/Physical Humor: Exaggerated physical actions, cartoon violence (like characters getting crushed or eyes popping out), and general physical mishaps are common, similar to the style of Looney Tunes.
Surrealism/Absurdity: The show is known for its quirky and often bizarre situations, non-sequitur jokes (e.g., Patrick screaming "Finland!" in "Frankendoodle"), and dream sequences that defy logic.
Wordplay and Dialogue Humor: The series features clever dialogue, puns, and memorable lines that are often quoted by fans.
Character-Driven Humor: Jokes arise from the distinct personalities of the characters, such as Squidward's dry sarcasm and cynicism, Mr. Krabs' extreme greed, and Patrick's blissful idiocy.
Satire: The show subtly satirizes everyday life, workplaces (the Krusty Krab as a dysfunctional fast-food restaurant), and human nature.
Innuendos/Mature Jokes: The writing often includes subtle, mature jokes and innuendos that go over children's heads but are appreciated by adult viewers.
Visual Gags and Facial Expressions: The show makes extensive use of highly expressive, character art and visual gags to enhance the comedy.
Running Gags: The series utilizes numerous running gags, such as characters saying "My leg!" when injured or the ongoing "Hello, is this the Krusty Krab? No, this is Patrick" phone calls.
Gross-Out Humor: The show uses visual gags often played for shock value, involving bodily functions, disgusting food, and scenes with unappetizing or slimy elements, as seen in clips showcasing everything from rotten patties to a pile of green goo.
