During the last of Beethoven's Ninth Symphony there is a 20 minute period where the bass violinists don't play. During one concert, the lead bass violinist suggested that they sneak out and go across the street to a bar and have a few drinks. They agreed, and crept quietly out and had a good time downing more than a few at the bar.
Finally, one bass violinist spoke up and said that they'd better get back, it was almost time. "Don't s'worry", hiccuped the lead, "I tied the last few pages of the conductor's score together and that'll hold 'em"
The bass violinists staggered back to their seats and got ready, and the audience noticed some problems.
One young lady asked her fiance, "What's wrong? The conductor is so nervous!"
The fiance replied, "Don't you see, don't you understand? It's the bottom of the Ninth, the score is tied, and the bassists are loaded!"
