''{{Seinfeld}}'' was, in the pre-Internet dark ages, ''the'' [[FountainOfMemes mother lode of memes]] (including, but by no means limited to):
----
* [[MadnessMantra SERENITY NOW!]] [[labelnote:Explanation]] George's father adopts this mantra for an episode to use whenever he is annoyed. It doesn't work.[[/labelnote]]
* '''NO TROPE FOR YOU!''' [[labelnote:Explanation]] The Soup Nazi and his cry of "NO SOUP FOR YOU!" became a massive snowclone meme, recognisable even by those who had never even heard of ''Seinfeld''.[[/labelnote]]
* Yadda, yadda, yadda... [[labelnote:Explanation]] A character starts to tell a story, and yadda, yadda, yadda, they skip over something either due to attempts at concealment or simple lack of interest.[[/labelnote]]
* Shrinkage. [[labelnote:Explanation]] The UnusualEuphemism for a penis shrinking in size when cold.[[/labelnote]]
** I was in the pool!
** It shrinks?
*** Like a frightened turtle!
* These examples are making me thirsty. [[labelnote:Explanation]] Kramer once had a brief experiencing at acting with the sole line "These pretzels are making me thirsty", which became a RunningGag throughout the episode.[[/labelnote]]
* [[NotThatTheresAnythingWrongWithThat Not that there's anything wrong with that.]] [[labelnote:Explanation]] Jerry and George are MistakenForGay, and spend the entire episode either denying the claims or stating this line.[[/labelnote]]
* BUT I DON'T WANT TO BE A PIRATE! [[labelnote:Explanation]] Jerry unknowingly agrees to wear a pirate outfit (puffy shirt) on national television, with this being his reaction.[[/labelnote]]
** [[RunningGag BUT I DON'T WANT TO BE A COWBOY!]]
* But at least he's the [[ADateWithRosiePalms master of his domain]]. [[labelnote:Explanation]]One episode was spent on a contest between the main characters on who could go the longest without masturbating, and ''not once'' was the word "masturbation" used, prompting an enormous amount of {{Unusual Euphemism}}s, this being the most popular.[[/labelnote]]
** But is he spongeworthy? [[labelnote:Explanation]] The contraception device Elaine uses is no longer produced, prompting her to hoard them and have far higher standards as to whether she has sex with someone due to limited supply.[[/labelnote]]
* Hello ... ''Newman''! [[labelnote:Explanation]] Jerry has this reaction whenever he encounters his SitcomArchNemesis.[[/labelnote]]
* Vandelay Industries. ("And you want to be my latex salesman.") [[labelnote:Explanation]] George invented Vandelay Industries whenever he wanted to impress someone. In fact he invented and researched an entire alternate persona, Art Vanderlay whom was an architect. Moe's, a mexican restaurant chain still has a meal named the Art Vanderlay.[[/labelnote]]
* Man hands. [[labelnote:Explanation]] [[MinorFlawMajorBreakup Every relationship any of the four were in ended swiftly when they discovered some inconsequential detail they couldn't tolerate, with one of Jerry's partner's man hands being the most famous]].[[/labelnote]]
* Festivus... for the rest of us! [[labelnote:Explanation]] The holiday George's father invented.[[/labelnote]]
* ''Giddyup''! [[labelnote:Explanation]] One of Kramer's {{Catch Phrase}}s.[[/labelnote]]
* Was that wrong? Should I not have done that? [[labelnote:Explanation]] George says this after he is fired from his job for having sex with his cleaning lady.[[/labelnote]]
* [[SarcasmMode Aww, that's a shame.]][[labelnote:Explanation]]Jerry's sarcastic comeback to Newman when he complains about something. Often used on the Simpsons forum No Homers.[[/labelnote]]
* I seriously hope you guys don't do this. [[labelnote:Explanation]]A particular screenshot of George holding a baseball bat with a smug grin has become popular on a certain ImageBoard, usually accompanied with greentext chastising readers for doing something.[[/labelnote]]
* Well the Jerk Store called. They're running out of you! [[labelnote:Explanation]] A [[ComebackTomorrow late comeback]] George comes up with to a co-worker's joke at his expense, which he spends all episode building up to deliver, only for it to fall flat.[[/labelnote]]
* The sea was angry that day, my friends - like an old man trying to send back soup in a deli. [[labelnote:Explanation]] George telling the story of how, while posing as a marine biologist, he was forced to rescue a beached whale.[[/labelnote]]

Believe it or not, I'm not home!]] [[labelnote:Explanation]] An answering machine message George creates to annoy his callers away, as part of an overall process of avoiding speaking to a girlfriend who wants to break up with him right before a Yankee gala George is looking forward to.[[/labelnote]]
* Who! Who doesn't want to wear the rrribbon!? [[labelnote:Explaination]] The scene in The Sponge where Kramer is mobbed by bleeding heart liberals for not wearing a ribbon during a anti AIDS walk. The meme is about people refusing to partake in chain challenges (such as the Ice Bucket Challenge) or trends (like adding the LGBT filter on profile pictures on Facebook after the national legalization of gay marriage in the US).[[/labelnote]]
