In her comment on the previous post, Patroclus was kind enough to compliment me on my modest facility with amusing headlines. It's thanks, I suppose, to many years' experience as a sub-editor, although even then the muse would desert me.
I once spent a couple of weeks working on Vox magazine, around the time that Echo and the Bunnymen reformed and released a new album. Three of us must have spent at least half an hour filleting dictionaries and thesauruses and hazy memories of minor characters in Watership Down before coming to the unanimous decision that, no, there is not a single feasible rabbit-related pun in the English language that has not been thrashed to death five times over. And that includes "Warren Piece".
In the end, I think we went for something along the lines of "OOH LOOK, THAT MR ECHO AND HIS BUNNY BLOKES HAVE PUT OUT A NEW ALBUM, THAT'S NICE, ISN'T IT?"
