Adolph Hitler's "outburst" scene from the 2004 film "Der Untergang" ("Downfall") is an excellent example of how a cultural event can go "viral" as an internet meme. Because the original film was in German, complicated overdubbing is not required; creation of a parody can be achieved by the simple expedient of superimposing fake subtitles.
Dozens of such videos can be located with a quick search of YouTube, including ones in which Hitler reacts to sporting events, computer problems, Obama, Palin, Brett Favre, losing his home to foreclosure, the use of the term "grammar Nazis," and even the existence of the parodies themselves. The most recent example, embedded above, has him ranting about another meme - the "balloon boy" hoax.

this was funny the first time I saw one of these videos ... and only the first time... now it just a tired old joke that won't die...
Like George W'a... wha'? too soon?
This meme is so thetic but I love it (although this one wasn't as funny).
