Robert Rankin is undoubtably very funny, but I find that he's almost always unable to construct an ending to his books. With the exception of
The Antipope (which asides from being hilarious, got me attacked by a group of zealous
Catholics in
Germany), and arguably
Armageddon: The Musical, his books tend to feature "
Christ, better stop here before it spirals out of control" endings, in which he breaks
the fourth wall to joke about all the plot holes left unfilled. This was fair enough the first time he used it, but using it for the latter two parts of The Armageddon Trilogy was just plain cheap.
But you really should read the
Brentford Octology and
The Armageddon Trilogy. I'm skeptical about his other works. You can't beat
Elvis travelling through time with a quantum sprout called
Barry.
"Bang!" said the explosion.
