Well, now you can do that... Sorta.
There's a number you can call to leave The Man himself a voicemail!
"Like praying, leaving a voicemail message is a way to organize your thoughts. It's a perfect combination for some contemplation."
Obviously you'll need a phone that can call out of the country since God isn't here in the US... But if you have a fancy phone that can, the number is +316-4424-4901.
The voicemail simply says "Hi, you are speaking to God. I'm not in right now so leave a message."
Should the creator get Genius of the Week?! It's very possible.
