The following invocation was printed in issue number 3 of Chaosphere magazine.
Though Cthulu is a HP Lovecraft creation this is a very power invocation that does work. I must warn you though when working with any old one you must clearly say while stating your Will ask for nothing negative. I have had a mix of good and bad experiences with Cthulhu. Bad things as in annoyances. Which is why you must make sure to ask for nothing negative to happen. Anyway enjoy!

Oh god of enjoyment thee I invoke
Oh high priest thee I invoke
Oh messenger of the old ones Thee I invoke
Son of nug Thee I invoke
Cthulhu fhtagn Cthulhu fhtagn Cthulhu fhtagn
That is not dead which can eternal lie.
And with strange aeons even death may die Thee I invoke
free and wild and beyond good and evil Thee I invoke
God of the Mi-Go. Thee I invoke
God of the Deep Ones Thee I invoke
By Yog-Sothoth, By Shubb Niggeruth, By Azathoth Thee I invoke By Dagon Thee I invoke
Cthulu,Satan,Shiatan,Set,lucifer,Tiamat,Levathan,Beezlbub, Typhon Whatever name I call thee let thy supreme enjoyment and chaos shine thru me oh Cthulu who will rise when the stars are right. Teach me your ways!
Cthulu Come thou forth and dwell in me and make all spirits subject onto me so that every spirit of the firmament and of the either above the earth and under the earth on dry land and in the water of whirling air and of rushing fire and every spell and scourge of the gods may be obedient onto me!
