This is getting a lot of press the last few weeks because Buzz Aldrin mentioned on CSpan. The actual photos are a few years old now. There are some odd items on the surface of Phobos (The vaguely potato shaped moon orbiting mars).
Bert from Sesame Street is evil and this site has the photo evidence. Sadly this site has been taken down but the internet archive has such great pics as Burt's mug shot, Burt at the JFK assasination and more.
