A recent meme is to mix up science fiction universes to provoke an indignant response from science fiction geeks. A quote from a movie, TV show, book, or video game will do, but make sure it's mis-attributed and laid over a picture that has nothing to do with the quote or the attribution! See 32 examples at Geekosystem. Link
I do like this meme though it is not funny at all if you do not know the origins of the quote and who is actually pictured.
I recently saw a pic of Steve Martin accompanied by Leslie Nielsens death notice - I felt a little dirty, but lolled anyway.
The other ones in the link didn't cause it at all- I must have a very specific stimulant aversion.
or it could just be the novelty of the situation, very nice.
