->'''Barats:''' You know what they say about men with big feet?\\
'''Car Insurance Agent:''' (sigh)... ''they have large penises?''\\
'''Barats:''' They're great drivers. Nice try though, ''pervert!''

A phrase often used to disparage X, where X is a group with a number of negative stereotypes associated with them. For example, "You know what they say about Jews", "You know what they say about black women", and so on. Can also apply to Sci-fi or fantasy settings, either as FantasticRacism or as a spoof; i.e. "You know what they say about orcs", "You know what they say about vampires," "You know what they say about [[Franchise/StarTrek Klingons]]." Often foreshadows a visit to a PlanetOfHats.

Alternatively, a phrase used to imply a specific correlation, based on people's familiarity with the phrase, and expectations (as in the page quote).

Usually, "what they say" is merely implied, but sometimes a person will elaborate on what stereotype they're talking about. This can lead to some humor, as another character assumes they're talking about a different stereotype, and the first character ''has'' to elaborate. ("You know what they say about the British!" "They love soccer?") (What, you mean that isn't it?) Since the phrase is often used to say something offensive without actually ''saying'' it, the speaker can often be flummoxed by a BluntNo and subsequent request that they elaborate.

Often leads to YouKnowImBlackRight. DoesntTrustThoseGuys is a subtrope; what they say about X is that you can't trust them.

* In 2010 or so, the United States corn refiners' lobby was running an [[http://www.sweetsurprise.com/ ad campaign promoting high-fructose corn syrup]], including TV spots like [[https://www.youtube.com/watch?v=KVsgXPt564Q this one]]:
--> "You know what they say about it."
--> "What?"
--> "It's... umm..."
--> "That it's made from corn, has the same calories as sugar or honey, and is fine in moderation."

[[folder:Film]]
* In ''Film/AHardDaysNight'', Paul's grandfather does this more than once. Once, he tries doing this to Ringo ''about Ringo'': "They'll pick on a nose, you know." But similar insinuations about fellow Beatles and cops later prove effective.
* ''Film/TheNunsStory'': "You know what they say about monkeys" *does the MonkeyMoralityPose*
* Applied to the Klingons in ''Film/StarTrekVITheUndiscoveredCountry'' with lines such as "they all look alike" and "only top-of-the-line models can talk". Irony was elicited from having a black Starfleet admiral claim that "Klingons would become the alien trash of the galaxy". Nichelle Nichols, however, refused to say "guess who's coming to dinner". That line was given to Chekov while Uhura's other line was to be "Would you let your daughter marry one?" was cut altogether.

[[folder:Jokes]]
* Creator/RobinWilliams: You know what they say about a man with big hands and big feet, right? [[spoiler:Right, big gloves and big shoes!]]
* Creator/JeffFoxworthy: "You keep hearing that, don't you? 'You know what they say about a man who's got big hands; big feet; big ears; big nose...' I tell you what, he ''better'' be packin', cuz that's one ''funny-lookin''' dude!"
* Another old joke: You know what they say about people with big feet? They have more [[{{Pun}} understanding]].
[[/folder]]

[[folder:Literature]]
* Spoofed a few times in the ''Literature/{{Discworld}}'' books:
** In ''Literature/WitchesAbroad'', Granny Weatherwax objects to Nanny Ogg wearing red boots, ending her criticism with, "You know what they say about women who wear red boots," to which Nanny replies, "Just so long as they also say they've got dry feet."
** In ''Literature/MenAtArms'', Constable Cuddy (a dwarf) overhears someone use the phrase "You know what they say about dwarfs!", and for several scenes afterwards demands to know what exactly people say about dwarfs because, of course, nobody tells ''them''.
*** When someone eventually ''does'' tell him, the general Discworld tendency for literal-mindedness (which is very strong in dwarfs) causes him to repeatedly misunderstand it.
** In ''Literature/{{Jingo}}'', Angua and Carrot find a suspect has a collection of weapons catalogues, and Angua jokes "You know what they say about men who like big weapons." Carrot, who's not one for dirty jokes, asks what, and after she awkwardly admits "They're rather... small", he thinks she means "short" (like dwarfs, who are known for carrying big axes wherever they go). At least, that's what he ''says''. Angua has her doubts...
** ''Literature/{{Hogfather}}'':
-->'''Archchancellor Ridcully''': You know what they say about bald men, Dean.\\
'''Senior Wrangler''': ''Yes,'' they say, 'look at him, he's got no hair.'
** ''Literature/TheTruth'' features a man named Mr. Windling who is a tenant at the place William de Worde lives, who likes to use this phrase. William de Worde, being an ethical journalist, [[RageBreakingPoint eventually gets fed up with this habit]] and demands that Mr. Windling tell him who "they" are and what "they" say.
* ''Literature/TheChroniclesOfNarnia'': "Fauns will say anything, you know."

[[folder:Live Action TV]]
* In the series premiere of ''Series/StarTrekVoyager'', Harry Kim is in Quark's bar and when Quark tries to sell him some junk says they warned him about Ferengi at the Academy. Quark responds by acting offended that slurs about his people are being taught and Harry is so flustered he starts offering to buy the junk. Paris has seen what is happening, leans in and examines one of the items, comments on how cheap it is, and rescues Harry. As they walk away Harry gives an embarassed grin when Tom says with a smile "Didn't they warn you about Ferengi at the Academy?"
* In the ''Series/PeeWeesPlayhouse'' episode The Cowboy and the Cowntess, Pee Wee notices Cowboy Curtis's boots are worn out and offers him his wish for the day so Jambi could give him a new pair of boots. Jambi asks what size and Curtis says something like 15 and then... DoesThisRemindYouOfAnything
-->Curtis: Well, you know what they say. Big feet... big boots!
* In ''Series/WakingTheDead,'' a character comments that the French are highly emotional. Boyd agrees and [[spoiler: glances at Stella as he does so. She's French. OK, British-born, brought up in France, but that's a discussion for elsewhere]].
* ''Series/{{NCIS}}''.
** From "My Other Left Foot":
--->'''Abby''': You know what they say about men with big hands and big feet...
--->'''Ducky''': What?
--->'''Abby''': They're clowns!
** Another episode involved TheMafia characters, who happened to have stereotypical Italian names.
--->'''[=McGee=]''': What do you expect with names like that?\\
'''[=DiNozzo=]''': ''(miffed)'' I dunno probie, what ''do'' [[YouKnowImBlackRight you expect]]?\\
'''[=McGee=]''': Uh...
* ''Series/TheFreshPrinceOfBelAir'': Will had his "baby shoes" lacquered to give to his mother on Mother's Day. When he shows them to the others they turn out to be ''adult sneakers''. When they point this out...
-->'''Will''': Yeah. I had big feet. And you know what they say about guys who have big feet!\\
'''Ashley''': What?\\
''[Will notices Phil glaring at him]''\\
'''Will''': ...they say "Damn, that guy has big feet!".

[[folder:Video Games]]
* In ''VideoGame/NeverwinterNights2'' (also an example of HypocriticalHumor):
-->'''Khelgar Ironfist''': Prejudiced? I'm not prejudiced! By the Nine Hells, I even travel with a back-stabbing tiefling of all things, and you know how her kind are!
* FantasticRacism abounds in ''VideoGame/WorldOfWarcraft'' and several [=NPCs=] will pull this on the player. On the world of Azeroth, racism comes in several flavors: Alliance-aligned characters who hate orcs, Alliance-aligned characters who hate undead, orcs who hate non-orcs, undead who hate the living, and anti-elf hatred (with an undercurrent of homophobia and victim blaming). Over the course of the ''Mists of Pandaria''expansion to ''VideoGame/WorldofWarcraft'' conversations between the player and Warchief Garrosh Hellscream get increasingly awkward due to the Warchief's casual racism towards all the non-orc races in the Horde. He doesn't realize that his statements are offensive to you if you happen to be a member of one of those races because he considers you ACreditToYourRace and not like the people he's complaining about. You are after all the big strong hero right? [[spoiler: not really]].

[[folder:Webcomics]]
* Subverted magnificently in [[http://maze.icomix.com/comicpage/browse.php?index=717 this]] ''Webcomic/{{Irritability}}'' strip.
-->'''Robot:''' Yeah, well... you know how politicians are.\\
'''Enne:''' ...able to be broken down and smuggled in suitcases?\\
'''Robot:''' Yes. I heard it on NPR.
* Played with in [[http://www.girlgeniusonline.com/comic.php?date=20050808 this strip]] of the webcomic ''Webcomic/GirlGenius'', with the three Jaegerkin discussing their becoming actors. Once they figure out that the Heterodyne stories have not one but ''two'' leading men, Maxim and Ognian are relieved because they ''both'' can play a leading man. What's so hot about being a leading man? Why, you get to kiss the girls. (The following exchange translated from the faux German accent. It's a great accent but a little hard for the uninitiated to read.)
-->'''Ognian:''' We'd be kissing actresses! And you know what they say about actresses.\\
'''Maxim:''' Well, um, no.\\
'''Ognian:''' Yah, me neither. But I bet we find out if--\\
'''Dimo:''' Quiet, you idiots! If they find out how irresistible we are to the women, they'll never let us join!
** Immediately after this exchange, the actors decide they ''are'' worth keeping on - as clowns.

* [[Literature/TheLayOfPaulTwister Paul Twister]] uses this to social-engineer his way out of getting caught by a guard: he pretends he's there for a tryst with the local sorceress, and "[[YouKnowWhatTheySayAboutX you know what they say about]] [[PowerPerversionPotential magic and the Nighttime Arts..."]] The guard is [[TooMuchInformation predictably squicked]] and stops being suspicious of him; instead just wanting him to leave, [[BatmanGambit exactly as planned.]]

[[folder:Western Animation]]
* Slight variant in this exchange from ''WesternAnimation/BeastWars'', after BigBad Megatron has proposed a truce.
-->'''Optimus Primal''': So you take me for a fool?!\\
'''Megatron''': No...I take you for a Maximal.
** Of course, Optimus takes the truce, but he knows Megatron is up to something, and from there, things get interesting.
** Also, during Optimus' unintentional suicide run at the Planet Buster, Megatron comments on his plan with this:
--->'''Megatron''': You Optimuses are always so eager to sacrifice yourselves for others.
*** The insult here being that all previous holders to the title of Optimus (such as Optimus Prime in G1) tend to jump on a whim into certain death to protect others and defeat a Megatron.
* In one episode of ''WesternAnimation/PinkyAndTheBrain'', Brain masquerades as an office worker, and a female co-worker comes on to him with the line, "You know what they say about men with big ears? They wear big earmuffs."
* Done twice in the Ms. Ellen episode of ''WesternAnimation/SouthPark''. Both times we never find out what the answer is.
* In the WesternAnimation/PhineasAndFerb epside, " Vanessassary Roughness":
-->'''Doofenshmirtz:''' You know what they say about taking the easy way...
-->'''Vanessa:''' ''(Exasperated)'' What do they say?
-->'''Doofenshmirtz:''' Well, I could tell you, but that would be taking the easy way, [[CircularReasoning and you know what they say about that.]]
