Maybe my favorite George Carlin bit - and worth listening to and scraping the brain plate clean over and over again.

"...Religion easily has the greatest bullshit story ever told. Think about it. Religion has actually 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 'til the end of time!
But He loves you...

...I want you to know, when it comes to believing in God, I really tried. I really, really tried. I tried to believe that there is a God, who created each of us in His own image and likeness, loves us very much, and keeps a close eye on things. I really tried to believe that, but I gotta tell you, the longer you live, the more you look around, the more you realize, something is fucked up. Something is wrong here. War, disease, death, destruction, hunger, filth, poverty, torture, crime, corruption, and the Ice Capades. Something is definitely wrong. This is not good work. If this is the best God can do, I am not impressed. Results like these do not belong on the résumé of a Supreme Being. This is the kind of shit you'd expect from an office temp with a bad attitude..."
