At approximately 9 a.m. (ET), Know Your Meme's main tubular network systems were suddenly brought down (reasons of which are still being investigated by the tubular network system cyber-security commission at this time) and as a result, the database is currently only capable of processing memes that were validated in time before the Internet as we know it, in time before the Internet meme was a thing.

The confirmed section of the Know Your Meme database (as of April 1st, 2013)

Given these circumstances, the Know Your Meme tubular network system cyber-security commission is hereby declaring a state of offline crisis, effective as of April 1st, 2013. You are now in a queue. The site will return to its normal operations once the tubular network system has been fully restored to its capacity.

In the meantime, please submit entries relating to memes that are outside the domain of the Internet. This means anything from postal chain letters, century-old pub songs and rock paper scissors to papermaking, Santa Claus and heck, even Marxism. Basically, the history of the human civilization is ours to document. If you're a "glass-is-half-full" kind of person, that's even kind of exciting. Now think big!
