(With one minor modification, adapted from a comment on Pharyngula.)

With a million fervent prayers combined
It won’t be long until you find
The mighty force that lies behind
The simple-seeming prayer.

The “clasp your hands and kneel” routine
Holds powers that are unforeseen
By heathens (and by that I mean
You, too!), but which are there!

So when they say “I’ll pray for you”
Remember, it’s a heady brew–
The Holy Spirit must come through,
You must already know.

And whether they are priests in collars,
Pastors, Rabbis, even scholars,
Remember–Prayer, plus five more dollars
Will buy a cup of joe.
