Help me find a (really well-known) comic

I have been googling like a mad thing but no joy. Annoying as I know it’s very popular.

Tone: quirky and occasionally a little sick
Feature: often shows round-headed people
Name: something to do with a church or a revival or something
Memorable strip: A dragon asleep on a Chinese hillside. Villagers dip the dragon’s hand in a bucket of water. Dragon pisses itself and floods the village.

I am predicting the answer in the first post below:

Perry Bible Fellowship. Funnily enough, it was linked to in a different thread and I was just reading it before seeing this thread.

Two minutes. That’s got to be close to a record.

This place rocks.

Excellent. Thanks!
