Religion — easily — has the Greatest Bullshit Story Ever Told! Think about it. Religion has convinced people that there’s an invisible man — living in the sky — who watches everything you do, every minute of every day. And the invisible man has a special list of ten things he does not want you to do. And if you do any of these ten things, He has a special place, full of fire and smoke and burning and torture and anguish, where he will send you to live and suffer and burn and choke and scream and cry, forever and ever, till the end of time! But He loves you! He loves you and he needs money! He always needs money! He’s all-powerful, all-perfect, all-knowing, and all-wise — somehow just can’t handle money! Religion takes in billions of dollars, they pay no taxes, and they always need a little more. Now, you talk about a good bullshit story, holy shit!

Religion -- easily -- has the Greatest Bullshit Story Ever Told! Think about it: religion has actually convinced people -- many of them adults -- that there's an invisible man who lives in the sky and watches everything you do, every minute of every day. And who has a special list of ten things he does not want you to do. And if you do any of these ten things, he has a special place, full of fire and smoke and burning and torture and anguish, where he will send you to remain and suffer and burn and choke and scream and cry, forever and ever, till the end of time! But he loves you. He loves you and he needs money! He always needs money. He's all-powerful, all-perfect, all-knowing, and all-wise, but somehow ... he just can't handle money! Religion takes in billions of dollars, pays no taxes, and somehow always need a little more. Now, you talk about a good bullshit story. Holy shit!
