"...the finest source of everything that's bizarre, odd and downright weird in books. We now have 101 crazy and strange titles about every oddball aspect of life you could possibly imagine and a few things you couldn't possibly imagine."
This assemblage is slightly different from the well-known Bookseller/Diagram Prize, which is awarded annually to the book with the most unusual title. In the AbeBooks room, some of the selections have rather prosaic titles, but unusual subject matter.
The example shown is The Teach Your Chicken To Fly Training Manual, in which "Using careful instructions, detailed diagrams and specially designed exercises to build up wing strength, Weekes guides you in training your chickens to take to flight."
You can probably find something more to your liking.
