From early cave paintings tens of thousands of years ago to the bathroom stall at our favorite bar, humans have probably been scribbling male genitalia on flat surfaces ever since we, as a species, first learned how to draw. While science has allowed us to do many great things, perhaps our finest moment came recently when NASA inadvertently drew a penis – captured in the image above – on the surface of the Red Planet. Checkmate to all you graffiti artists out there.

While this might seem like a comical stunt dreamed up by the guys over at Top Gear or even the geeks from Big Bang Theory, this is actually the result of Mars Rovers Spirit and Opportunity leaving tire tracks on the surface of the Red Planet. Although the drawing is said to be accidental, we'd like to imagine that some of the smartest people on the planet operating the equipment still have an incredible sense of humor.

      I see the basics for a Far Side cartoon here. Just need to add the giggling scientists back on Earth.

      "I believe that this nation should commit itself to achieving the goal, in the next 50 years, of landing an unmanned module on Mars and using that module to depict upon the Martian surface the image of a giant human penis."

      It looks like NASA was doing donuts with the rover up there:)

      I think now we really know who was behind this incident from a couple weeks ago:

      This is a direct challenge to the Russian, European and Chinese space programs. They'll need to draw even larger phalli to out-do the USA.
