What is a meme?

Dawkins, who coined the word, said:

Examples of memes are tunes, catch-phrases, clothes fashions, ways of making pots or of building arches.

It doesn't have to be an online quiz, it doesn't need to be a set of questions, it's an idea, a saying, that is passed on, person to person, until everyone has heard it or read it. I have a new one. Well, sort of:

"I would so love to be quoted, one day, by someone."
