There's a guy who had a life long dream to visit Africa. He finally gets the chance to go. The moment he steps off the plane he hears drums off in the distance. He goes to the baggage claim and gets his luggage then catches a cab.
On the way to his hotel, he's talking with the cab driver and tells him how happy he is to finally get the chance to visit Africa, and how the drums off in the distance really set the mood and give an authentic feel to the country. They arrive at the hotel. He pays the cab driver and the cab driver tells him to enjoy his stay.
It's now the last morning of his two week vacation and he has noticed that the drum beat he heard when he first got there has been going 24/7. The cab arrives to take him back to the airport, and wouldn't you know it, it's the same cab driver. The cab driver drives him to the airport. As the driver helps him remove his luggage from the trunk of the cab, he asks the driver a question.
VISITOR: "The drums were cool at first, but they never stopped. Do they ever stop?"
CAB DRIVER: "The drums never stop."
VISITOR: "They never stop! Why not?"
CAB DRIVER: "If drums stop, something terrible happens!"
VISITOR: "What?"
CAB DRIVER: "Bass solo!"
