Thanks @vince, I had to remind myself that fractal veggie.

@Pete well cheese doesn't fly but flying cups, bowls, pans, egg timers or blenders, hmm... ;-)

Flying blenders? Well, like the priest said, who visited Steve's farm... Holy Crop!

I remember seeing one of these fresh at a local farmer's market and I had to buy it.  It was the most beautiful thing ever.  Screw gifting flowers, imagine receiving one of these for a change.

I ate it raw like broccoli and it tasted like crap, compared to broccoli it's very hard and is relatively tasteless but whatever taste there is it's not very good, I ate the entire thing anyway (not at once).  Maybe it's better cooked?

It'll be the Librarian who writes about this. Are crop circles pure art? ... or are they ... simulation of a real thing?! OOooOOOOo

I don't buy what the BBC documentary says, there's something real about crop circles.

I had something that captured my imagination once, but my wife refused to pay the ransom to get it back. Hey, two dollars is two dollars.
