I still say elvis is the prime subject, those shifty rockabilly eyes, and allways wearing jumpsuits, on star treck all the aliens wear jumpsuits, ELVIS WEARS A JUMPSUIT=HE IS AN ALIEN=HE DID THE CROP CIRCLES
but more seiously, if it was aliens why in heck would they fly god knows how many lightyears to a backwater arm of the galaxy only to artisticly damage Mr johnsons corn crop, are they inter galactic stoners? is it Alien Graffiti saying something along the lines of \"Zeevox blows Xentalsees\", was it the people who showed it was a hoax by admitting they did it and how. or was it somethig so sinister its evil can only be seen in a small amount of property damage.
or is it all a conspiracy
