Homogeneouly similar to its predecessor, it too features a few repetitions and some nonstarters (humour may be subjective but some of the 'jokes' can't even charitably called that), but overall the quality of the jokes are fair (though not the subject matter, the joke book certainly wouldn't be called politically correct).
The section on graffiti was different fare from the usual joke book material. Truly unique was a detailed 'dictionary' at the end that featured all sorts of puns and wordplay - if you are getting fed up with the book and thinking of giving up on it, make sure you go to the end and read that bit first.
