{{quote|''"'All wood burns,' states Sir Bedevere. 'Therefore,' he concludes, 'all that burns is wood.' This is, of course, pure bullshit. Universal affirmatives can only be partially converted: all of Alma Cogan is dead, but only some of the class of dead people are Alma Cogan."''|"A Lesson in Logic", ''[[Monty Python and the Holy Grail]] (Soundtrack from the Motion Picture)''}}
|"Logician" (track 9), ''The Album of the Soundtrack of the Trailer of the Film of [[Monty Python and the Holy Grail]]''}}
 
:: Claiming a quality of one thing is also a quality of another thing because they have some other thing in common, e.g. "Water is a liquid. Water will put out most fires. Therefore, any liquid will put out most fires." And then you pour on the olive oil. Or the high-proof vodka.
Line 12 ⟶ 14:
* Sweeping Generalization
 
:: Guilt By Association assumes that two separate things share a negative factor because they share a different, unrelated factor. (See also [[Stop Being Stereotypical]], [[Don't Shoot the Message]])

Line 49 ⟶ 51:
Because Jesus is Good, Jesus only does and associates with Good things (again, [[Rule of Cautious Editing Judgment|there are flaws in the logic best left alone]])
Ergo, because alcohol is Bad, Jesus never partook of it. }}
::In order to make this work, any time wine is referenced in a positive context (for example, Jesus' first miracle), the word is instead rendered as "unfermented grape juice" when translated into English.
* ''[[Squid Girl]]'' has Cindy Campbell show off this fallacy in her first appearance: Squid Girl has tentacles; some aliens that Cindy has heard of have tentacles; therefore, Squid Girl is an alien. (Cindy also mentions that she graduated at the top of her class at MIT, but that's [[Appeal to Authority|a different logical fallacy]] in play.)
 
=== [[wikipedia:Reductio ad Hitlerum|Reductio ad Hitlerum]] ===
:: A very common form of Guilt by Association is "Hitler did it, therefore it's bad." While persuasive, it's not always true, since while Hitler did a lot of evil things, he also was a massive advocate of animal rights (well, definitely more so than Jewish, gay, or Gypsy rights...), built motorways, painted pictures, hosted the Olympics, [[Hitler Ate Sugar|ate sugar]], and breathed oxygen. This is related to the Fallacy of Division, since it assumes the evilness of the whole of Hitler also applies to any part of Hitler. Related to [[Godwin's Law]] and [[Hitler Ate Sugar]].
