Although I'm not a huge poetry fan -- I tend to like my prose, and stick with my prose, and be happy with my prose -- I do want to recommend this delightfully disgusting book:
Now We Are Sick: An Anthology of Nasty Verse, edited by Neil Gaiman and Stephen Jones.
It's set up much like a Shel Silverstein or Jack Prelutsky book of verses, but the reading material is definitely oriented toward the child inside of the adult. From the ghoulish to the gorey, there are giggles aplenty throughout. At 108 pages (of verse), it's a quick and enjoyable read.
Why am I posting about it here? While it's certainly not a fairy tale, the writers have drawn on that substance from which the best stories are made -- fear of things that go bump in the night, and the dark side of humanity that feeds those very bumpers. With nods to other authors, like Lewis Carrol ("You're Deceased, Father William," etc), this book is definitely one you want to get your hands on.
