AS crop circles come, the one shaped like a plug caused more than a little stir.

It had enthusiasts in a frenzy, talking about electro-magnetic fields and the symbolic significance of the crop formation.

Of course they were talking nonsense. This, like all crop circles, was man-made.

Not that it makes the phenomenon any less interesting.

Crop circles are incredible artworks that should be celebrated as such, and Weetabix should today be congratulated for the most ingenious publicity stunt of the year.
