The Surprising Adventures of Baron Munchausen

The two halves were clearly different authors. The first half I quite enjoyed; the stories were short and ridiculous and the deeds boasted of were witty and entertaining.

The second half was quite tedious, both in its sesquipedalian writing style and its content, and the boasting was more about how everyone loved him and endless references to other works.

I'd definitely recommend reading just the first half and ignoring the fan faction second half.
