One from Mike Fenton this last weekend -

Travelling through the amazon jungle in a canoe, the explorers heard the sound of drumming. They turned to their guide and asked what this meant.

"Drumming good. Tribe happy. No worries. When drums stop, that bad"

Further up river, the drumming suddenly stopped, and the explorers saw their guide cowering in the bottom of the canoe, shivering.

"Drumming stopped. Next come autoharp solo"
