A couple of enterprising bass players, unwilling to sit through a long, bass-less stretch of Beethoven's Ninth, sneaked off stage and into the bar next door. Beer flowed; time passed. "Look at the time! We have to get back!" said one. "Relax," said his partner, "I tied the last few pages of the conductor's score together with string. It will take him a few minutes to untangle it." They staggered back into the hall and took their places. About this time, a member of the audience noted that the conductor was breaking a sweat. "Of course," replied her companion, "It's the bottom of the Ninth, the score's tied, and the bassists are loaded".
