A Biologist assigned to work in deepest Africa hired a guide to take him upriver to the remote site where he would do his study.
As they were making their way into the jungle, the scientist heard the sound of drums.
"What is that drumming?" he asked his guide nervously. The guide replied, "Drums OK, but very bad when they stop."
The drumming continued for two weeks while the biologist conducted his fieldwork.
Finally, on the last day, the drums suddenly stopped, and the forest fell eerily silent.
Alarmed, the scientist called out, "The drums have stopped! What happens now?"
The guide crouched down, covered his head with his hands and, with despair in his voice, answered, "Bass solo. "
