It's enough to make you nostalgic for "All your base are belong to us".

Do you know your internet memes?

"Rewind back to early 2000 or the late 1990s," said Know Your Meme editor Brad Kim. "This is around when the word 'meme' slowly and gradually became associated with ... interesting internet stuff."

Memes, for the uninitiated, are "any online media that spreads on a massive scale across the internet", Kim said. Many, he said, come from TV, popular movies, video games - mainstream culture. "That is the single biggest source of internet memes." See Know Your Meme's top 10 list below. (Note: The language in some images in the meme video below is not always family friendly.)
