BBC:

A Massachusetts man who was rushed to hospital with a collapsed lung came home with an unusual diagnosis: a pea plant was growing in his lung. Ron Sveden had been battling emphysema for months when his condition deteriorated. He was steeling himself for a cancer diagnosis when X-rays revealed the growth in his lung. Doctors believe that Mr Sveden ate the pea at some point, but it "went down the wrong way" and sprouted.

That's LIFE!
