From the October ’05 issue of Outside Magazine:

I was attempting an unsupported solo trek to the North Pole in 2000. The first day, my sled slipped into the sea and I had to reach into the water to get it. My left hand was gone after that, so I held my stove with my mouth to light it. The steel froze to my lips. Then the tent caught fire. Back home I amputated my mummified fingers with a saw. I’ve still got them.
–Veteran British explorer Sir Ranulph Fiennes
