An orchestra is playing Beethoven's 9th Symphony. There is a passage in the middle when, for about 20 minutes, the bass violinists have nothing to do.So they decide to slip out to a bar and drink a few beers. After a while one says, "Hey, we better get going."But another says, "No, wait. I tied several pages of the conductor's sheet music together, so we'll have a couple of extra minutes while he sorts it out."So they stay for another round. Finally when they go staggering back to their places. It was the bottom of the ninth, the score was tied, and the bassists were loaded.
