A Chinese guy was skipping rocks across a lake one day. A Black man came by and asked what he was doing?
He said, "You skip the rock across the water and it will tell you your ancestors."
Watch. He skipped a rock across the water and it said, "Ching, Chang, Zing!"
The Black guy said, "Let me try that."
He skipped a rock across the water and it went, "Chim Pan Zees!"
