Here's one stanza of a "bad joke song" from Garrison Keiller:
One morning, the devil came to church,
In a burst of smoke and flame,
He ran up and down the aisle.
He said, "Beezlebub is my name.
I am evil incarnate,
The objects of all your fears!"
The old man said, "You don't scare me at all,
Been married to your sister for 48 years."
