Cartman's Church
Cartman's Church is a Christian church founded and built by Eric Cartman that appeared in the Season Four episode "Probably".
Background
In order to prevent themselves from being sent to Hell when they die, The Boys enlist Cartman as a preacher and have him build a church to live without sin. When Kenny calls The Boys from a payphone in Ensenada, they believe he is really calling from Hell and they ask him what it is like, much to Kenny's confusion. Back at the church, Cartman describes to the other kids what "Hell" is like and when one of the kids' fathers is killed, he believes it is God speaking to them and he leads the others into a prayer.
Later on, it is revealed by Cartman that the church and his preacher act were all a scam to con the other kids out of their money. Cartman continues with the scam until Sister Anne brings Jesus to the church, who explains that God doesn't want them to be afraid of Hell and he wants them to live a happy life. The other kids leave the church with Cartman trying to get them back, but he is then sent to Ensenada by Jesus.
