I like this story. Received this from a co-worker...pretty funny...

The minister was preoccupied with thoughts of how
he was going to, after the worship service, ask the congregation to
come up with more money than they were expecting for
repairs to the church building. Therefore, he was annoyed to
find that the regular organist was sick
and a substitute had been brought in at the last
minute. The substitute wanted to know what to play.

"Here's a copy of the service," he said impatiently.
"But you'll have to think of something to play
after I make the announcement about the finances."

During the service, the minister paused and said,
"Brothers and sisters, we are in great difficulty;
the roof repairs cost twice as much as we expected,
and we need $4,000 more. Any of you who can pledge
$100 or more, please stand up."

At that moment, the substitute organist played "The
Star-Spangled Banner."

And that is how the substitute became the regular organist!
