Meh. I thought this was a thread about the very first song in mankind's history.
I know what it is too. I saw it in a movie.
A bunch of cavemen were passing along rocks, bucket-brigade style. Caveman A failed to catch and the rock lands on his foot.
Caveman A screams: "Aaaaaa...!!!"
Everyone stops. Caveman B, standing next to him, approaches with a puzzled look. Suddenly, he thinks of something. Grabbing another rock, he drops it on Caveman C's foot.
Cavemen C screams: "Aaaiiieee...!!!"
Caveman A brightens up. Grabbing yet another rock, he drops it on Caveman D's foot.
Caveman D screams: "Yeeeaaarrgghh...!!!"
Caveman A smiles. He has a new idea. He calls everyone together and tells them his plan.
Several days later, the entire tribe is assembled, everyone has several rocks in his/her hand, and Caveman A is standing in front, facing them. On his signal, they start throwing rocks at each other's feet. Their combined screams sounded out:
"HAAAALLELUYAH!!! HAAAALLELUYAH!!! HALLELUYAH! HALLELUYAH! HALLEEEELUYAAAAH....!!!"
