The Bunny Suicides 

This originated as a picture book by an author whose parents gave the name Andy Riley. Then again he might have chosen that name as a pseudonym. Anyway, that's beside the point. There are now a number of websites that have the illustrations of that book.

Anyway, each illustration feature a bunny who goes about finding the most ingenious, unnecessarily awkward and hilarious ways to terminate his life.

There is one catroon where the bunny leans against a wall and holds a nail up to his forehead. In front of him he has placed a huge ice-block, and embedded in the ice-block is a hammer attached to a string. His plan is that the sun will melt the ice causing the hammer to swing towards the nail driving it through his head.
