I have the perfect cure for sleepyness.

Get ten of the fathers of the missing children and get two lengths of rope. Give each rope to five of the fathers to hold and tie one end of each rope to this guys testicles.

Get the fathers to take up the slack and if this guy starts to nod off ask the fathers to give a gentle waking tug on the rope…

If somehow by accident the ropes somehow come free or remove something then they should be reattached to another part of his body… leaving the neck till last and genitals first…
