Ping, you have a real knack for rhyme. Here's one I think I found from a thread on this site, but I don't remember from who...
God, many believe, is immutable,
And their faith is, indeed, irrefutable:
When He does what He should,
It's because "He is good,"
When he doesn't, "His ways are inscrutable."
Edit: one more...
From out of the crypt of St. Giles
Came a scream that resounded for miles
The Vicar said "Gracious
It's Brother Ignaceous
He's forgotten the Bishop has piles"
