While it's still not possible to download a Halloween costume, stepping away from the computer for a few hours to trick or treat or go to a costume party doesn't mean you have to leave the Internet behind. In fact, Know Your Meme has come up with a guide to dressing up as your favorite online meme. They have instructions for everything from Keyboard Cat to the Flying Spaghetti Monster to that rabbit with a pancake on his head.

Unfortunately, because you can't trick-or-treat the Internet (yet), you and your friends might be the only ones who think your costumes are funny. To be fair, though, some of them are really, really funny, and going door-to-door with your kid dressed as the pancake bunny is a guaranteed candy goldmine.

If you're planning to dress up as an Internet meme or something software-related - anybody going as the Mozilla Firefox? - let us know in the comments. And post some photos if you've got them. This is the Internet, after all: pics or it didn't happen!
