BTW, reportedly there was a headless chicken!

It was called Mike and lived for 18 months after its head was chopped off!
Here's his official story:

The Amazing, true story of this famous fowl dates back to September 10, 1945 when Mike, a young Wyandotte rooster, was about to become the dinner of Fruita, Colorado, farmer Lloyd Olsen.

With a sharp ax in hand, Mr. Olsen firmly held Mike, preparing to make the bird ready for his wife Clara's cooking pot. Mr. Olsen swung the implement, thereby lopping off poor Mike's head. Mike shook off the event, then continued trying to peck for food.

Mike's will to live remains an inspiration. It is a great comfort to know you can live a normal life, even after you have lost your mind.

Thanks, Mike!
