Have you tried making one of these things? Not as easy as it looks. I have started publishing what I consider to be the better ones here once a week. Here is No. 12.
If you’d like to see more, here is the “Geek-themed Meme of the Week Archive”.
And if you’d like me to consider one that you’ve found – or created – please feel free to send it to me at email@example.com.
