I couldn't find any good videos online of the ritual chanting and hypnotic rhythm, but here is the basic script.

Concentrate game:

Two people play. One person sits behind the other. The person seated has their eyes closed and is silent. The second person sitting behind them says:

(Every time they say this, they pound lightly on the person’s back with both fists) Concentrate. Concentrate. Concentrate on what I’m saying. People are dying. Children are crying. Concentrate. Concentrate. Concentrate on what I’m saying. (Verse 1: Tap the person on the top of their head with your fist and run your hands down both sides of their head) Crack an egg on your head. Let the yolk run down. Let the yolk run down. Crack an egg on your head. Let the yolk run down. Let the yolk run down. Concentrate. Concentrate. Concentrate on what I’m saying. People are dying. Children are crying. Concentrate. Concentrate. Concentrate on what I’m saying.

Then it gets creepier…

(Poke the person, then mimic running hands down both sides of their back) Stick ten needles in your sides. Let the blood drip down. Let the blood drip down. Stick ten needles in your sides. Let the blood drip down. Let the blood drip down. Concentrate. Concentrate. Concentrate on what I’m saying. People are dying. Children are crying. Concentrate. Concentrate. Concentrate on what I’m saying. (Tap them on the back with their fist, then run their hands down their back) Stab a knife in your back. Let the blood drip down. Let the blood drip down. Stab a knife in your back. Let the blood drip down. Let the blood drip down. Concentrate. Concentrate. Concentrate on what I’m saying. People are dying. Children are crying. Concentrate. Concentrate. Concentrate on what I’m saying. (Mimic wrapping a rope around their neck and then pull the imaginary rope. The person’s head should move back as if they are being hung.) Wrap a rope around your neck. Wrap it till it’s tight. Wrap a rope around your neck. And… PULL!

As if this is creepy enough, now you tell them that they’re on the top of a building and someone pushes them off- The person narrating this entire thing pushes them and quickly asks “What color did you see?”… and THAT determines how they die:
