Scoop is one of the funniest books out there! I haven't read it for years - thanks for reminding me of it.
A modern book I thought was very funny, although not quite as innocent, was "The Lecturer's Tale," by James Hynes. It is a satire on the pretensions of modern academic life and has some howlingly funny moments.
I haven't read Scoop but if it's his funniest it must be hillarious.
