You see, memes are so dynamic that you can never truly have a favorite meme. Their life spans are extremely short, so much that textbooks on them became obsolete within months. Compare that to computing systems, and you'll find that memes are created and stop being used in cycles many factors higher than that of microprocessor speeds and data storage capacity.
In addition to this, not only are the life cycles dynamic, so too are the mentalities behind them. Our society's earliest memes, their nature discovered some forty years ago are next to unrecognizable to us today, lost in a fresh wash of the near-endangered captioned reaction photo, and the dank vine, which thankfully is ending its short-lived life. To continue the analogy, the most computer systems operate in exactly the same way that they did on their inception; this is understandable as the laws governing the function of electronics do not change, and memes have no laws. Pressing on, the fundamental architecture that makes computers work has only been shrunk, rather than changed, though new methods are appearing as we speak on the horizon. A meme example of this would be the use of integrating known memes, such as "troll face" and "y u no" into "rage comics" and never proceeding past that milestone.
In conclusion, you may assume you have a favorite meme, but I can assure you in six month's time you'll have little to no recollection of today's memes, and will be on to new cancer. I leave you with my favorite meme, a mere imprint of an international generation's struggle
