After a relaxing holiday at the Forest-side Nature Hotel, shopkeeper Gengis Kahn feels his personality has expanded so substantially that he decides to write a self-help manual.
If only he could find a shop that will sell him a biro...But he soon discovers that the road to publication and posterity is littered with the potholes of the modern world.
Gengis narrowly avoids being replaced by a clone of himself after spending a year on a life support machine, and is forced to fake his own death to escape life imprisonment for calling a cheerleader 'Popsickle'.
He encounters an entrepreneur who seems literally to have crawled through excrement to reach the top, and fights in vain against the destruction of the rain forest to supply wood for the world's toilet seats.
This hilarious final part of Gregory Motton's comic trilogy mixes swoops of imaginative absurdity with acutely observed set pieces from everyday life, firing satirical arrows at the overweight targets of consumerism, mediocrity and greed.
