When the drumming

A man goes to an exotic tropical island for a vacation. As the boat nears the island, he notices the constant sound of drumming coming from the island.

As he gets off the boat, he asks the first native he sees how long the drumming will go on. The native casts about nervously and says "very bad when the drumming stops."

At the end of the day, the drumming is still going and is starting to get on his nerves. So, he asks another native when the drumming will stop.

The native looks as if he's just been reminded of something very unpleasant. "Very bad when the drumming stops," he says, and hurries off.

After a couple of days with little sleep, our traveller is finally fed up, grabs the nearest native, slams him up against a tree, and shouts "What happens when the drumming stops?!!" "Bass solo."
