The Symphony Orchestra was playing a concert in the park. They were in the middle of Beethoven's 9th Symphony. The basses, in the back of the orchestra, decided they had a few minutes to spare before being asked to play anything, so they ran across the street to the pub for some ale. It was a windy day, so they found some string to wrap around their music stands to secure their music while they were gone. Once at the tavern, they could hear the music and keep up with the progress of the piece.
After a few rounds, they decided that they had to hurry because
the last movement of the ninth symphony was under way. They stumbled
back onto the bandstand and were fumbling with the string, trying to get
it loose, but not having much success. The conductor saw what was
happening and instantly sized up the situation: it was the bottom of the
ninth, the score was tied and the basses were loaded.
