Well, it could have been the last thing that anybody around to report it heard
him say. Seems pretty unlikely, though...
The BBC documentary series The World At War
has interviews with people who were in the bunker with Hitler when he died, including his driver (who was one of those who found the bodies) and his secretary. If anybody reported this then it would probably be one of those two; they didn't in the interviews I've watched so far.
