Peter's reply when told he faced certain death at the hands of Captain Hook was "Now that really would be a great adventure"
This does not appear in the many reprints of the book but strangely Disney used it in the film "Hook" in a slightly altered form.
As a child I was taught that "Death is the Last Great Adventure" and it came from a very old copy of Peter Pan that my mother owned. Thus it was explained to me when my mother's parents died that they had gone on a Last Great Adventure.
