Return of the Bunny Suicides (2004) is the second bestselling book of black comedy cartoons by Andy Riley that depict the various ways bunnies attempt to kill themselves.
The term "Heath Robinson contraption" is used in Britain, in exactly the way "Rube Goldberg machine" is used in the U.S.
This book also contains more parodies of various recent cultural and historical events of the time.
For example, there is one image of a bunny tying himself to Gollum, seeking the ring at the top of the hill, and also a bunny pouring pepper into Sauron's eye from The Lord of the Rings, and an image of the falling Saddam Hussein statue, and a scene with the Doctor (from Doctor Who).
The book proved so popular that pirate scans started to circulate heavily online as "Bunnies Suicide" prompting the publisher to send a DMCA request to Google, which was indexing the site and its images.
