The RickRoll is probably the greatest of all internet memes, but internet, far too much time has been spent doing it. A good old Excel spreadsheet and a batch of YouTube search data has produced this:
That is to say that, incredibly, mankind has spent over 750 years being RickRoll’d. Basically its like Rick Astley’s face having been around since 1255. It really scares me. However, using the same approximation, Justin Bieber’s Baby has been played for 4000 years.
UPDATE: Haha, I’ve just calculated that the Nyan Cat has traveled around 500,000km based on it traveling 400 pixels a second on a 96dpi screen (this is an approximation).
