does anyone know what episode of south park retold how books in bible where written?

[Richard]

I saw an episode years ago that retold a story about a man that talked to god in a cave or something. Then he came back to tell people about it and wrote it down. Then they took the copy of what he wrote down and told him to write it again so he went back to the cave or whatever it was and tried to write the same story again but he couldn't because obviously he was lying so he just said another man talked to him and wrote a different version. and this happened a couple times and this was suppose to explain how there are different stories in the bible. I thought that episode made a lot of sense so i kind of wanted to see it again but I havn't been able to find it. Thanks
