The New York Times describes an Internet meme as "an idea, image, catchphrase or video that goes viral, mutating via amateur remixes into unexpected forms." Over the past ten years, as we've seen the rise of new means of sharing content, like YouTube, Twitter, and Facebook, the outpouring of memes has been staggering.
From pranks and parodies, to pithy one-liners and oddball photographs, netizens have dished up and passed around a fair share of hilarity over the last decade.
