I caution you before continuing that what you are about to read could be quite offensive.
With so many porn films based on popular movie titles, I came up with a great list (before HBP came out) for the Harry Potter movies.
Hairy Peter and the Sorcerer's Bone
Hairy Peter and the Chamber of Dark Secrets
Hairy Peter and the Prisoner of Ass Cabana
Hairy Peter and the Corset of Fire
Hairy Peter and the Order of the Penis
Hairy Peter and the Half-Formed Penis (new at the time of the book)
Hairy Peter and the Deathly Hollows (just came up with, may need some work)
Have fun.
