DNF. I have a decided aversion to comedy based on social embarrassment, particularly the kind resulting from mistaken identities and similar misapprehensions, so I got a couple of chapters in and then had to give up. (I picked it up because of the comparisons to Three Men in a Boat, which I had really enjoyed, but it's a distinctly different style -- the comedy in  Three Men in a Boat is, if anything, based on the fact that the main characters are completely immune to social embarrassment, which I find much more relaxing.)
