unfortunate

The guy who had to cut off his arm after getting it pinned between two boulders while hiking has come out with a book entitled "Between a Rock and a Hard Place."

10% - chance I think I'd be able to convince myself to cut off my own arm with a pocket knife in that situation.
90% - chance that, if I did, I would write a book about it.
100% - chance I'd be able to avoid using a pun in the title.
