We all know how memes work, at least intuitively. They start with an original work, e.g., the jingly earworm of All Your Base Are Belong to Us, and mutate in theme if not in form, e.g., All Your Base Are Belong to Rumsfeld/Halo/Spartaaaa! (Can I just tell you, por favor, how much I'm in <3 with the Sparta meme?)
So the original work, which stands alone, becomes a framework for successive iterations, each of which can be seen as an argument for a different phenomenon. In the examples above, Rumsfeld's army overran Iraq, Halo fever gripped the gamer world, and the hirsutely homicidal visage of Gerard Butler was (is?) ubiquitous. (The combo of the Base and Sparta memes may = a memeplex, if you want to be a fundamentalist about it. In which case, I'd call Base the nuclear DNA, and Sparta the mitochondrial.)
IOW, memes are like mad libs. Just fill in the ______.
Which brings me to my favorite current meme, The Downfall. The videos have been circulating for a few months now, at least, but it wasn't until I saw The Downfall of the Cowboys iteration by Cracked, and subsequently The Downfall of HD-DVD, that I realized how devastatingly awesome this meme is, to wit: The Downfall video is a mad libs for syllogisms.*
Quoting Desi, lemme 'splain: The Downfall meme concerns a clip from the original film in which Hitler's generals explain to him the Allies' inexorable march towards Berlin. Hitler gets peeved, yells copiously about why Germany is losing, and collapses into exhausted dejection. "The war," he says, "is over."
Now take that scene, remove the English subtitles -- the original's in German, which is why the meme interpretations work -- and add any argument whatsoever. Why the Cowboys lost. Why Blu-Ray bested HD-DVD. Why the AMPTP is the great satan. Whatever's clever, they all work.
The humor part's easy. Juxtapose the world's most vicious dictator with a transient theme and you'll get chuckles. But even more devastating: the argument's presented from the losing side, from the lips of the most reviled human ever, and has the weight of historical inevitability. Who better to explain why someone/something lost than to put the reasoning on the tongue of Hitler? The Cowboys lost b/c they're Hitler. HD-DVD lost because its Hitler. The AMPTP is Hitler. :)
So that's a mad lib for syllogisms. I guess the opposite meme would be one based on the Bud Light sausages commercial. WTF, you haven't seen that? It's only the best thing ever of all time. Gary Larson, you almost got it right.
*I'm no logic expert, but I'm pretty sure The Downfall argument is an example of a syllogism. Original premise (we're screwed), supporting evidence (the Allies are coming), conclusion (the war's over). If I'm wrong, somebody drop some knowledge.
