Ok, this is a pretty good joke I heard from the bass player in my band. There is a reasearcher walking through the savanna in Africa. He is trying to find his camp when he hears drums in the distance. He walks towards the drums and finds another reasercher camp. When he enters one of the other reaserchers welcome him. The man tells him he is welcome to stay as long as he wants. Then the (original) reasercher asks "Why do you constantly play these drums?" The man replies "If we don't something bad will happen." So the reasercher stays for a couple days, fighting the loud drums every night he tries to sleep. When one day he wakes up and the drums have stopped. When he steps outsied he notices everyone is runnig around if fear. When he sees the man he talk to origanlly he asks "What's the problem?" The man replies "Every time the drums stop something bad happens." The reaserchers ask again "Well, whats the problem?" The man replies "Don't you know? Every time the drums stop there is a bass solo."
