The  minister was preoccupied with thoughts of  how he was going to 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!
