Curiosity on Mars Draws Naughty Pictures

Caption This

NASA recently published pictures from Curiosity's track patterns, and the Mars rover appears to have traced out a very penis-like design on the dusty surface of the alien planet, complete with balls, lol...

According to HuffPo, the "car-sized rover landed on Mars last August with a mandate to explore the planet and analyze whether or not Mars could have supported life forms. Curiosity is controlled by a team of NASA engineers, who send two sets of instructions to the exploratory craft each day."

If you ask me, I don't think Curiosity made that pattern by mistake, my guess is those engineers are being very naughty :)

So who can best caption the picture?
