The Chronicles of Blarnia is full of low-brow jokes, toilet humour and childish asides. None of this prevents it from being one of the funniest things I've ever read - indeed, I just finished it and have been chuckling noisily for hours.
Okay, some of the parody elements are particularly moronic - take Asthma the Messianic house-cat, the overweight Wide Witch or young Ed with his overweight-ladies fixation - but Michael Gerber always follows a bad gag with a fantastic one. What's most surprising is that the joke's impact is sustained throughout. And when Gerber repeats a joke he usually follows it with a knowing wink.
He may have ruined the recent film for me (I'll have this fresher in mind than C.S. Lewis' novel), but at least I got a fun read out of it. Hysterical, and hugely recommended.
