1. Locate Satan. (Recent searches have shown that he lives in a dorm in Manhattan)
2. Upon locating him, hit him up on his cellular telephone. He will ask you the following: "Be ye angels?" Calmly reply "Nay, we are but men."
3. He will then try to eat your soul. Respectfully remind him that you have no soul because you sold it to him. Provide him with the receipt (you did get a receipt, right? if not... forget it)
4. Then you have to schedule an appointment with his secretary, which by the way is Christopher Reeves.
5. The meeting
a. Offer him your firstborn.
b. Agree to listen to him pout about how he has no soul.
c. Then perform three tasks (these vary depending on the soul seeker, I had to dance with a small baboon and perform several other humiliating tasks that I'd rather not discuss)
6. Then you sign an agreement that outlines the terms of soul retrieval. Which says that he will slowly supply you with your soul until the birth of your first child, at which point he will return your soul in its entirety.
That's it. Good luck. Luckily Satan doesn't know that my firstborn is an alien. HAHHAHAHAH! SUCKER!!!! Can't believe he fell for the old "get my soul back for an alien baby" trick.
