* One episode, after the opening sequence finished, Garfield said "[[Series/WheelOfFortune I'd like to buy a vowel, please.]]"
** Another post-opening sequence line was "The Garfield Guarantee: No [[{{Transformers}} giant robots]] or [[TheSmurfs annoying little blue people]]."
** Still another was "If you change the channel, you will never see your dog again.", referencing the famous "Buy this magazine or we'll kill this dog" January 1973 cover of ''National Lampoon''.
** Another one of these quotes had Garfield say "This show is [[Series/SesameStreet brought to you by the letter K and the number 9.]]"
* In one episode, Garfield opens the door and says [[ActorAllusion "Hello, this is Garfield, your doorman."]]
* Garfield has to deal with a ghost and thinks maybe "I can call the [[WesternAnimation/TheRealGhostBusters The GhostBusters. Nah their show was cancelled.]]"
* From the episode "Read Alert":
Wade: "Oh ''Series/{{Jeopardy}}!'' Oh '''Double Jeopardy!''' Oh '''FINAL JEOPARDY!'''"
* Cactus Jake...or should I say Cactus [[Wrestling/{{WWE}} Jack]]?
* Also doubling as a BrickJoke: in one episode, Garfield & Nermal contend with mutant guppies, who they defeat by chasing them back into the sewer. Said guppies then appear in the subsequent US Acres Quickie; after scaring Wade and Orson, one guppy turns to his fellows and says "Come on guys, let's go see if we can get a guest shot on the MuppetBabies, whaddaya say?" (Muppet Babies aired after the show on CBS at the time).
* Aloysius Pig is KevinMeaney in a pig costume. They both even share two catchphrases! [[note]]"That's not right!" and "I don't care!", even though the latter was only said once[[/note]]
* In "Clash Of The Titans", as the gang is flying home, Garfield asks if the characters can stop at ''WesternAnimation/{{Teenage Mutant Ninja Turtles|1987}}'' so they can get a pizza.
* In "Temp Trouble", we have this line: "Mrs. Pig, it's Saturday morning. Do you know where your children are?". Ironically, the thing the quote shouts out to [[note]]A message broadcast on TV at 10:00PM[[/note]] was based off Wee Willy Winkie, [[{{Foreshadowing}}was a nursery rhyme that would be spoofed 8 episodes later.]]
* In "The Discount Of Monte Cristo", Aloysius [[spoiler: wants Series/{{Flipper}} to rescue him from being stranded on an island.]]
* In "Kiddie Korner", Aloysius says that sitting on a tuffet "sounds naughty". This could be a reference to a Dot's Poetry Corner segment of {{WesternAnimation/Animaniacs}} that aired a year before this episode, where Dot reads Little Mrs. Muffet and uses "tuffet" as a euphemism for "butt", [[PantyShot while showing us her panties doing so.]]
* Newsworthy Wade has a ShowWithinAShow called "7 Minutes", a spoof of Series/SixtyMinutes.
* In a weird example of the show having a shout out to itself, one US Acres quickie had Roy on a stage in a competition involving baaing and cocking against Lanolin. One season later, the same stage reappears in the Laryngitis quickie, and he stands on it in almost the exact same manner!
* In "Much Ado About Lanolin", the scene where Lanolina trips on her dress is quite similar to the scene in ''WesternAnimation/SantaClausIsCominToTown'' where Burgermeister Meisterburger trips on a duck in exactly the same way. Lanolina, however, did not get her foot in a cast, but yelled at how the stairs were defective.
* One rather silly episode has the entire episode purposely having animation errors. At the very end, Garfield leaves and Odie follows, except Odie is ''NewspaperComic/{{Marmaduke}}''
* In "Flat Tired", while deciding who to get for the cartoon when Garfield is too tired, the director initially says "Get me [[Franchise/{{TheMuppets}} Kermit The Frog]] on the phone," before choosing [[ADayInTheLimelight Odie]]. Also a bit of an in-joke, since WesternAnimation/MuppetBabies was also on CBS at the time.
* In "Peace and Quiet", Binky refrences the United States Post Office motto, "Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds", but replaces "couriers" with "clown".
