Darwin: Well, love is in the air. It's in your heart, in the eyes of others. It's in the way people touch, the way people talk. And it's all over the universe.
Bobert: If I understand you correctly, you have narrowed the definition of love down to everything and everywhere and everyone.
Gumball and Darwin help Bobert learn what love is, which turns into a Vignette Episode showing the trials and tribulations of love.
Tropes:
- Bait-and-Switch:
- One vignette is an educational video-like segment with a narrator scientifically explaining the chemical reactions of Love at First Sight between a male and a female subject. At the end they're seen hooking up with members of the same sex that have been off screen the whole time, to the narrator's moderate surprise before accepting the fact that love has no set rules and ends the segment with the lovers dancing.
- Another segment features the cheese guy holding a sandwich and describing how he feels, but then it turns out he wants to talk to Karen rather than describing the sandwich.
- Black Comedy Burst:
- When the female version of the Moon tries to join the Sun on the other side of the Earth, we hear people screaming (most in French) and she apologizes to the Sun for flooding Europe.
- Margaret fakes being terminally ill just so she can shock her husband with a defibrillator and put him in the hospital.
- Richard's attempts at hugging people gets him arrested and tried in court for alleged sexual harassment (hugging Felicity) child molestation (hugging Billy), and assaulting a police officer (hugging the Hamburger Cop), then put in jail where he's punched into the hospital by his cellmates (though his family does visit him in the hospital). The music and how Richard happily hugs people despite the consequences is what makes it funny.
- Bowdlerise:
- Cartoon Network's Polish channel censored the "Love is Chemistry" segment to remove the last part, which revealed that the man and the woman used in the demonstration are gay and lesbian respectively and the announcer concluding that love has no set rules and that everyone should just dance.
- Over in Spain, the European Spanish dub curiously omits the female vocals heard during the vignette in which Richard's hugging people lands him in trouble. It's curious because the title card has the female vocals that were omitted.
- The Cartoon Network Asia version cuts the sequence with Sussie's parents having dinner (most likely due to the gross-out humor).
- Dictionary Opening: Most of the skits open with a screen giving different dictionary-style definitions of love.
- Cargo Ship: It turns out Bobert had fallen in love with a vacuum cleaner.
- Formula-Breaking Episode: This episode does not have a storyline to it (whether self-contained or part of an arc), but is rather a Vignette Episode with musical number bookends.
- Go-Karting with Bowser: Rob/Dr. Wrecker is among the people singing the Love song.
- Incurable Cough of Death: Mrs. Robinson coughs several times before she is sent to the hospital. Played for sick laughs, in that Margaret faked being terminally ill just so she can prank her husband.
- Jerkass Has a Point: While the Hexagon Lady is creeped out over Timmy knowing everything about her, Timmy is right in saying that she shouldn't post everything about herself online (which is what leads creeps like Timmy to know everything about someone).
- Literal Metaphor: An Internet dating site in one vignette is literally a site where you hook up with The Internet/Timmy himself (he has a Guy Fawkes profile picture).
- Meaningless Meaningful Words:Darwin: Well, love is in the air. It's in your heart, in the eyes of others. It's in the way people touch, the way people talk, and it's all over the universe!
Bobert: If I understand you correctly, you have narrowed the definition of love down to "everything" and "everywhere" and "everyone". (error sound) Does not compute. - Mistaken for Pedophile: Richard hugs Billy who has fallen off his bike, and his mom catches him, concerned over his safety. Richard then hugs Felicity and she calls the cops on him.
- Shout-Out:
- The Robinsons vignette parodies the Happier Times Montage from Up.
- The skit that educates on the physical changes from being love has background music that sounds suspiciously like Wii menu music.
- The music that plays during the title card and when Richard hugs everyone sounds like MGMT's "Electric Feel".
- The judge who convicts Richard is a more-or-less family-friendly version of Judge Arse.
- Slap-Slap-Kiss: One segment is about the Robinson's relationship as it developed, with a Shout-Out to Pixar's Up.
- Special Guest:
- The sketch about the science behind love was narrated by Simon Day.
- David Warner was credited in the beginning for appearing in this episode, in a brief appearance as Rob the cyclops/Dr. Wrecker.
- Vignette Episode
- The first part is Gumball, Darwin, and some other students and teachers trying to teach Bobert about love.
- The second part is the hexagon lady dating The Internet in an “Internet dating site”.
- The third part is a narrator explaining love only for some stick figures to be gay with each other.
- The fourth part in Nicole being asked why she loves Richard and not being able to come up with an answer, she just does love him.
- The fifth part is Sussie’s parents eating and being romantic which grossed everyone else out.
- The sixth part is Richard hugging Billy, Felicity, cops trying to arrest him, the judge of his trial, and the inmates in his prison cell.

- What Does She See in Him?: One segment has Nicole asked why she loves Richard. She can't come up with an answer, but she loves him anyway.
- What Is This Thing You Call "Love"?: What Bobert wants to know. Not only does the whole school answer him in song, but each vignette in the episode is a demonstration of a dictionary definition for his benefit.
