Leonard Slatkin, new music director for the National Symphony, prides himself on having the largest collection on conductor jokes in the world. This one is paraphrased from an interview he did with with NPR: ---- So the new conductor addresses the orchestra. He tells them that things are going to change, that everyone will be expected to be on time and that they will work for many long hours. The timpanist, expressing his displeasure at the turn of events, belts out on the drums BOOM-BOOM- BOOM-BOOM. The conductor, whirling around furiously, says, "Alright, who did that?!"
