"... dogs come from the ''moon'', not the Sun!"

Alice says something ridiculous. Bob responds with this StockPhrase (or some close relative), then explains ''why'' Alice's statement is ridiculous. Of course, Bob's justification is either as absurd, more absurd, or otherwise not a rebuttal one would normally make to the original statement.

Often, Bob is TheDitz, a {{Cloudcuckoolander}}, or a BunnyEarsLawyer. Less often, Alice is likewise one of those characters.

A common variant is that Alice's original statement was an attempt to guess what Bob is planning or doing. ("So you're going to just storm the castle?" "Don't be absurd. I'm going to storm the castle ''carrying this marionette.'' Sheesh.")

Not quite the same as the usage of the phrase by FunnyForeigner Balki Bartokomous in the sitcom ''Series/PerfectStrangers''. (He would say it when suspected of doing something wrong, but usually wouldn't follow up with a nonsensical rebuttal.)

See InsaneTrollLogic. Somewhat related to VoodooShark (when RealLife fiction-creators are seen doing this themselves -- albeit not in response to a theory they find absurd). May also involve DistinctionWithoutADifference ("No, I'm not eating an eraser. I'm eating ''two'' erasers"). Compare WorryingForTheWrongReason ("Sharks? Don't be silly. The crocodiles will get you first").

'''Yomi:''' [[PoesLaw ...are you for real?]]
* ''Manga/GAGeijutsukaArtDesignClass'', when the upcoming class is doing sketches in charcoal:
-->'''Nodamiki:''' And you need mayonnaise too!!\\
'''Tomokane:''' Mayonnaise?\\
'''Nodamiki:''' So I can put it on the crusts... and eat them![[note]]Bread is used as an eraser in charcoal drawing.[[/note]]\\
'''Tomokane:''' ''[holding up peanut butter]'' You don't use mayonnaise for the crusts!!\\
'''Kisaragi:''' Tomokane-san, that's not what you should be arguing about!!

* In ''Film/MuppetTreasureIsland'', Kermit/Smallett asks who hired the crew full of obvious pirates. Everyone points to Fozzie/Trelawney, while he points to his own finger.

* In ''Tea With the Black Dragon'' by Creator/RAMacAvoy, during Martha's first conversation with Mayland Long, he tells her a version of the tale of Thomas the Rhymer, which continues past the usual ending point to talk about Thomas' son. When he finishes, she remarks that he tells it with such authority she could almost believe he'd had it from Thomas in person.
-->"From the Rhymer?" He leaned forward and lifted his eyebrows in mock wonderment. "How could that be? ... I have the story from the boy, of course. The Rhymer's son.\\
"Beautiful boy," he added, after a moment. "Resembled his mother."

-->'''Fenchurch:''' And the answer is no.\\
'''Arthur:''' Fine.\\
'''Fenchurch:''' I was conceived there.

* In ''Discworld/{{Jingo}}'', Colon confuses "hieroglyphs" for a type of mollusc, and when Nobby asks "so if we go any deeper, they'll be loweroglyphs" Colon tells him not to be ridiculous, because everyone knows you don't ''get'' loweroglyphs in these waters.
* [[TheWonka Willy Wonka]] in ''Literature/CharlieAndTheChocolateFactory'' is fond of these. But given Wonka's absurdity, it goes over everyone's heads.
-->'''Mrs. Gloop:''' He'll be made into marshmallows in five seconds!\\
'''Wonka:''' Impossible! Unthinkable! Inconceivable! Absurd! He could never be made into marshmallows!\\
'''Mrs. Gloop:''' And why not, may I ask?\\
'''Wonka:''' Because that pipe doesn't go anywhere near it! That pipe -- the one Augustus went up -- happens to lead directly to the room where I make a most delicious kind of strawberry-flavoured chocolate-coated fudge...

'''The Doctor:''' Fairyland? Oh grow up, Lily! Fairyland looks completely different.

** Two accountants make a bet with each other as to which clerk will fall past their office window next:

''[cut to letter]''\\

* ''Radio/TheGoonShow'' - in "The Dreaded Batter Pudding Hurler", Henry Crun and Minnie Bannister discuss shooting elephants (out of season, no less) in Sussex. The announcer then adds this:
-->'''Wallace Greenslade:''' Listeners who are listening will, of course, realise that Minnie and Henry are talking rubbish; as erudite people will realise, there are no elephants in Sussex. They're only found in ''Kent''...

* ''Webcomic/DarthsAndDroids'', when the characters are surrounded by enemy ships:
-->'''Qui-Gon:''' I've got an idea!\\
'''Obi-Wan:''' It's not SummonBiggerFish, is it?\\
'''Qui-Gon:''' Don't be stupid! That would only take one or two hits, at most. Tell them we're bringing up a load of the Queen's laundry.
** Later on, on several occasions, Jim (who plays Qui-Gon) would suggest Summon Bigger Fish as a solution to the various problems they were facing. The DM would always have an objection ("You're not Qui-Gon anymore," "Luke doesn't know that power," "You're in space," etc.), but ''Summon Bigger Fish isn't an actual Jedi power in the first place.'' Ben always responds:
--> '''Obi-Wan:''' ''That's'' your reason for not letting him do it?
* In ''Webcomic/TheOrderOfTheStick'', Roy has suggested that Elan sleep, but Elan is too worried to sleep. So...

** In the cartoon "Cool Things", the following exchange occurs when Homestar spots Strong Sad through a pair of CoolShades covered in wet yellow paint.

'''Strong Sad:'''' What? I'm Strong Sad. Dripping Yellow Madness moved away after the fifth grade.
* WebVideo/TheNostalgiaCritic would like to clear up something about ''WesternAnimation/{{Anastasia}}'' in his "Top 11 Villain Songs" review:

[[folder:Western Animation]]
* ''Disney/AliceInWonderland'', when the Mad Hatter is "fixing" the White Rabbit's watch:

* In one episode of ''WesternAnimation/CodenameKidsNextDoor'', the episode ends just as Numbuh Five tells the other kids [[TheTalk where babies come from]].

* From the ''WesternAnimation/DarkwingDuck'' episode "Twin Beaks" when Launchpad (trying to get in touch with his aura) makes a detour in a cow pen.

'''Darkwing:''' Ooh, did the nice cow tell you all that?\\
'''Launchpad:''' Don't be silly, DW; this log gave me the directions. The cow just warned us not to order the coffee.
* Tennessee Tuxedo frequently says "Don't be ridiculous" when Chumley says something obtuse. Tennessee's ensuing thought would make as much if not less sense.
