I want a slower frames version, with a zoom feature... so I can see Steve on his tractor, making those crop circles. We all know it's him!!!

I lost a good first officer, adrift in space that way. I yelled to Ensign Steve, "Engage the tractor beam! To which he immediately went to the shuttle bay, and engaged the headlight on the John Deere. Oh well.

- Pete out.

As Steve's attorney, I have to warn you against stealing his intellectual property. You know, ROTATING CROPS.

Help! I'm in a flat spin.......

Ha! Dav now I know what the aliens saw just before they crashed in Roswell ;-))

Well I think the current crop circle design is getting old and we need to zap some new ones.

Some ideas:

I have a comic I photoshopped to a site once regarding the Roswell incident.

It was a saucer, half embedded in the ground at a 45-degree angle, and around the hull of the saucer, I printed "Student Flyer"
