Flush out your best toilet humour to win a signed copy of The Happy Bowel

To celebrate the publication of Dr Michael Levitt’s book The Happy Bowel, Fremantle Press is giving away four signed copies to the people who come up with puns so crappy they’ll make us bust a gut. We want you to dig deep and push out some bombs for us to share online.

We don’t care if you’re mining the bowels of the earth or scraping the bottom of the barrel, just send us your favourites for your chance to win.

Dr Levitt, highly respected surgeon, has restored hundreds of patients to bowel health and happiness. His fun and friendly guide is full of practical advice, helpful tips and clear explanations for how to obtain and maintain a successfully working bowel.

One rule: No swearing.

The competition is running over on Facebook page and Twitter @FremantlePress, or just email your puns to admin@fremantlepress.com.au

Winners will be announced on Monday 11 June.
