Here's a weekend diversion for you, its a game I used to play in the pub. Not very highbrow I'm afraid but can be quite funny - here are the rules:
1. Take the name of a book
2. Replace last word with 'bumhole'
Some to get you started:
The much loved children's book 'James and the Giant Bumhole'
Dickens' classic 'A Tale of Two Bumholes'
Aldous Huxley's 'Brave New Bumhole'
Over to you
