Though a lot of people wouldn’t find this heart-warming, I did: an Australian veterinarian, David Blyde, ended up putting his arm into the jaws of a grey nurse shark to remove a steel fishing hook, saving the animal’s life.   The three-meter shark was spotted off the coast with the hook protruding:

Seaworld diver Trevor Lond lassoed the shark, which was brought in for a team to work on.  Blyde had the seemingly scary task of actually reaching in and removing the hook (though he was protected by a pvc tube which had been first inserted).  Video of the process can be seen on CNN here.  The shark was released to continue a life of eating various things that it shouldn’t.

The grey nurse shark is a lovely creature which, despite its appearance, isn’t particularly hazardous to humans (though some attacks have been reported).  It is, however, one of the most endangered species of sharks (with possibly as few as 500 in Eastern Australia), which makes this rescue of a female an especially happy success story.
