I’ll put this one to you as simply as possible. It’s a picture from one of the Mars rovers that appears to show a person (or a rock), walking along the Martian surface. This person (or rock, probably) looks so much like that classic Big Foot picture that it makes me laugh. Anyway, this Martian person (or rock, honestly I think it may be just a rock everyone) is going all over the web, so I thought I’d put my two pennies in: I think it’s a rock.
