Liber Call Me Al (The Book of the Inlaws) is a really funny parody of Liber AL vel Legis, which was first published around 1988 in volume III of the 'Baphomet Breeze', a periodical of the no longer existing Baphomet Lodge in L.A. You still find copies on the internet. Check out volume III, number 2 for an equally hillarious 'Thelemic Language Lesson' that still mirrors a lot of the attitude amongst Thelemites. ;-)

Old, but I still find it hilarious and good fun.
