What is the somewhat-logical term for the internet prank and meme in which an unexpected appearance of the music video for the 1987 Rick Astley song 'Never Gonna Give You Up' is 'planted' into an unrelated link? The meme's popularity dates back to 2008.

The term meme was introduced in 1976 by British evolutionary biologist Richard Dawkins (author of "The God Delusion"). He conceived of memes as the cultural parallel to biological genes and considered them as being in control of their own reproduction.
