A meme is not just a picture with words, or a cartoon. My understanding is that it has to be a fairly common or popular image, with different text to go with it.
How this thread has a sidebar discussion of Darwin I don't quite understand.
Meme:
- 1.
an element of a culture or system of behaviour passed from one individual to another by imitation or other non-genetic means.
- 2.
an image, video, piece of text, etc., typically humorous in nature, that is copied and spread rapidly by Internet users, often with slight variations.
