History YMMV / FamilyGuyS13E1TheSimpsonsGuy

** Marge and Lois see a fictional sequel to 2007's ''WesternAnimation/SurfsUp''. Two years later, an ''actual'' sequel was announced, then released one year later in 2017 (albeit it was DirectToVideo).

* CounterpartComparison: Between Homer and Peter, Marge and Lois, Bart and Stewie, Lisa and Meg, Maggie and Chris, Brian and Santa's Little Helper, Kent Brockman and Tom Tucker, Mr. Burns and Stewie, Mayor Quimby and Adam West, Principal Skinner and Shepard, Smithers and Bruce, Bumblebee Man and Consuela, Dr. Nick Rivera and Dr. Elmer Hartman, Krusty the Clown and Mort Goldman, Seamus and Cpt. [=MacAllister=], Cleveland and Carl [[spoiler:and both versions of James Woods.]] Subverted by Quagmire and Lenny.

** The stolen car wash scene serves as this, both in and out of universe. It involves Homer and Peter, but overweight and plain-featured older men, doing the "sexy car-wash routine", clad in skimpy female tops & shorts with lots of slow-motion closeups of them grinding and pouring water over themselves and jiggling their flab.

* TheyWastedAPerfectlyGoodCharacter: Many fans of both shows were disappointed about the Marge, Lois, Brian, and Chris hardly do anything or interact with each other. All they do is take part in a few quick gags with no lampshading of similarities/differences between these characters.

* HilariousInHindsight: Matt Groening had objected when Fox requested a crossover with ''WesternAnimation/TheCritic'', feeling it was nothing more than a ratings stunt that he even took his own name off the episode. Now we have this special which is ironically an hour longer which, even more ironically, Matt had no problem with.

* DudeNotFunny: In-universe. Part of the crossover deal is to show what different standards of BlackComedy both shows have - whereas ''Family Guy'' often rely on [[RefugeInAudacity over-the-top violence]] and overly vulgar humor, ''The Simspons'' has always been somewhat lighthearted by comparison (doesn't mean they don't have dark humor though, look at the ''Treehouse of Horror'' series). The Simpsons family react accordingly to their respective counterparts because of this. Bart is weirded out when Stewie makes a rape joke phone call to Moe, and kidnaps all of Bart's enemies; Nelson, Jimbo, Principal Skinner, Sideshow Bob and [[OddNameOut Apu]] (although [[ActuallyPrettyFunny Bart gets a good laugh at Stewie saying]] [[JustForPun he "took Apu"]]). Lisa is creeped out by Meg risting in her name on her arm so she'll always remember her (although, when you know [[ButtMonkey Me]][[TheWoobie g]], it's kind of justifiable).

** Stewie one-upping Bart's prank call by calling Moe and telling him his mother is being raped has an uncomfortable bit of RealitySubtext, in that [[https://www.youtube.com/watch?v=8H-cB-l3O-4 this is more or less how the infamous "Quagmire rapes Marge" gag was conceived]]: it was Seth [=MacFarlane=]'s "little shot back" at ''The Simpsons'' for... [[DisproportionateRetribution accusing them of plagiarism]].

** The stolen car wash scene, both in and out of universe.

* AuthorsSavingThrow: When asked about Quagmire, Homer has no idea who he is - effectively applying either a DiscontinuityNod or full-on CanonDiscontinuity to the ''Family Guy'' episode where Quagmire rapes Marge and murders the Simpsons family.
** Realistically, though, no one should ever take a cutaway gag as canon unless it's explicitly referred to in a later point in the series. That gag, while absolutely horrible, was most likely never in canon to begin with, and was a result of the shows' writing team going overboard in their TakeThat to ''The Simpsons''. Even Seth MacFarlane stated that he regretted letting it be put in afterward the episode aired.

*** Actually, Homer and Peter being left to duke it out in Ned Flanders's absence speaks to the rise of belligerence and moral decay in the world.

** Peter's TheReasonYouSuckSpeech. ''The Simpsons'' not being as good as it used to be is not a unique complaint. It's practically a BottomOfTheBarrelJoke. And while few will disagree, or even feel that ''Family Guy'' has been mostly good in the time that their competition has lost steam, to many others, it comes off as the pot calling the kettle black, especially since there were complaints of ''Family Guy'' [[SeasonalRot rotting]] as early as it's [[{{Uncanceled}} uncancellation]] while ''The Simpsons'' at least has the excuse of [[LongRunner being on the air for nearly three decades]] for the strain on it's creativity.

** Peter's TheReasonYouSuckSpeech. Yes, fans have gone on record mentioning ''The Simpsons''[='=]s SeasonalRot in their complaints, but that largely due to being a LongRunner and opinions vary when it happened. But the ''last'' person they want to hear it from is Peter whose fans have been complaining of his show going downhill since it came back from cancellation... in season four (though the Writers Guild strike from 2007-2008 is really when the show started to deteriorate in quality, since season five is considered by some fans to be better than season four. Everything after season five is very hit or miss, with seasons six, seven, and ten being a big miss while eight and nine were hits).

* HarsherInHindsight: Creator/HarryShearer refusing to take part in the episode out of protest, now that he's officially quit the show. Considerably less so now that he's back.

* LightFeminineDarkFeminine: Marge and Lois respectively. One is a sweet-natured, modest woman who isn't into edgy media and is frightened when she sees penguins surf in animated films. The other is perverted, snide, bitchy, and doesn't wear a bra.
* NauseaFuel: The stolen car wash scene, both in and out of universe.

** JerkassWoobie: Stewie might be a psychopath but is completely heartbroken after Bart won't be his friend.

* HarsherInHindsight: HarryShearer refusing to take part in the episode out of protest, now that he's officially quit the show. Considerably less so now that he's back.

** Inevitable, but the main source of contention being that it really swings more toward the Family Guy cast rather then on really focusing on both families.
** Likewise some fans didn't like Family Guy's brand of humor [[{{Pun}} bleeding]] into the Simpson universe.

* FanficFuel: It's only used as a one-off gag to lampshade the setup, but you have to admit, a crossover between AllInTheFamily and ModernFamily would be pretty hilarious in its own right.
