"Drumming on a Remote Island" joke

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 on and is starting to get on
his nerves. So, he asks another native when the drumming will stop.
The native looks as if he has 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 tourist is finally fed up, grabs
the nearest native, slams him up against a tree, and shouts, "What happens when
the drumming stops?!"
The scared native answers, "Bass solo."
