There's a Facebook page titled Honest Album Art and it's pretty much the best page on the Internet. What they do is exactly what it sounds like they do- take the album art of any given album and re-title it however they see fit in accordance with how the music sounds. I took fifteen of my favorites off the page, not including the Sleep parody above, and put them into a little list for you! Enjoy, and try not to laugh too hard! Also try not to get mad. It's all in good fun!
