Here's a pretty unique mashup for you to enjoy. Artist Justin Lawrence DeVine has a Tumblr where he posts all sorts of cool artwork that he has produced. And one particular series that he's done is a mashup of characters from The Muppet Show and the David Lynch cult classic Twin Peaks.
Here's a sampling. There are more on his Tumblr page along with lots of other great artwork.
