Rock...

found on Mars, shock. Last week news was dominated by a rock. Scientists were aghast that Martian terrain might feature rock. "We planned for everything but this." Said an ashen faced engineer.

A local who would not give her name told  reporters, "Thank you people of Earth for this huge thing that's landed. We've no idea what it does. Send duvets next time eh? It gets cold this far from the sun, dontcha know."  Asked about the rock she replied. "Damn thing, people are always tripping over it."
