Because it’s funny.
Update 07/22/12: I guess I need to put some background information about this image as I have an international following. The image is of Fozzie The Bear who is a character of in the The Muppets. Fozzie is carrying two other characters headed toward Mordor. You can find more information on the Muppets from Wikipedia. I’m not going to explain Mordor as then you’ll never find it funny because chances are you’re not a geek.
