Meme's are alive!!! muhahahahaha!

Propagating through evolution of natural selection. Catch-phrases never sounded so intellegent!

From Wikipedia (of course)

The term "meme" (IPA: [miːm], not [mɛm], or [mimi]), coined in 1976 by Richard Dawkins, refers to a unit of cultural information transferable from one mind to another. Dawkins said, Examples of memes are tunes, catch-phrases, clothes fashions, ways of making pots or of building arches. A meme propagates itself as a unit of cultural evolution and diffusion — analogous in many ways to the behavior of the gene (the unit of genetic information). Often memes propagate as more-or-less integrated cooperative sets or groups, referred to as memeplexes or meme-complexes.

The idea of memes has proved a successful meme in its own right, achieving a degree of penetration into popular culture rare for a scientific theory.
Proponents of memes suggest that memes evolve via natural selection — in a way very similar to Charles Darwin's ideas concerning biological evolution — on the premise that variation, mutation, competition, and "inheritance" influence their replicative success. For example, while one idea may become extinct, other ideas will survive, spread and mutate — for better or for worse — through modification.

Meme-theorists contend that memes most beneficial to their hosts will not necessarily survive; rather, those memes which replicate the most effectively spread best; which allows for the possibility that successful memes might prove detrimental to their hosts.
