Also, I must mention that Bogleech
has a really hilarious article on The Book of Vile Darkness
, making fun of all the stupid in it (except for, unfortunately, THE NIPPLE CLAMP OF EXQUISITE PAIN!), and I highly recommend you check it out.
Also, there's a 9th level spell in "Exemplars of Evil" named "Ring of Fire". Not sure if it counts, but I find the idea of a spell named after a Johnny Cash song hilarious and am eagerly awaiting a 9th level Necromancy spell known as "Ghost Riders in the Sky"
