Although raised in the Roman Catholic faith, Carlin has often denounced the idea of God in interviews and performances, most notably with his "Invisible Man in the Sky" and "There Is No God" routines. In mockery, he invented the parody religion Frisbeetarianism for a newspaper contest. He defined it as the belief that when a person dies "his soul gets flung onto a roof, and just stays there", and cannot be retrieved.
Carlin has joked that he worships the Sun, because he can actually see it, but prays to Joe Pesci (a good friend of his in real life) because "he's a good actor", and "looks like a guy who can get things done!"[39]
Carlin also introduced the "Two Commandments", a revised "pocket-sized" list of the Ten Commandments in his HBO special Complaints and Grievances, ending with the additional commandment of "Thou shalt keep thy religion to thyself."[40]
