Sometimes, PopCulturalOsmosis only works part of the way, and as a result, certain famous works or events are only known for one or two lines.

To make things worse, a show which attempts to [[ShallowParody parody]] said event will only include that one line.

Often the result of NeverLiveItDown, and is a common cause of ItWasHisSled. If this phenomenon is blown out of proportion enough that the original context seems to become irrelevant, it's MemeticMutation. See also CommonKnowledge. For the InUniverse trope where most characters know about an alleged secret, see EverybodyKnewAlready.

A lot of these will also be mentioned in the SignatureLine or SignatureScene pages.

'''The Game'''

Underneath each item is a list of "stock facts" that everybody seems to know about a person, place, event, or work. Try to guess as many of them as possible before looking at the spoilers. Double points if you know the specific significance or context of each fact.

Possible answers will be:
* The premise
* Events
* Specific details or facts
* Well-known quotes
* Completely incorrect information which somehow got associated with it. (Triple points for these, if you both know it and understand why it's wrong!)

'''Guideline when adding new entries:''' It must be something that ''the majority of people'', not just you, or a specific niche of the fandom, are able to recall from memory.

Also, you may add an explanation if you so choose, but it's not mandatory.

Finally, despite the fact that EVERYBODY seemingly knows these things, '''they should be spoiler tagged'''.
