Delicious Demon

One person calls someone to pour the water,
Because it takes two to pour the water,
To plough takes two as well,
But only one to hold up the sky.
One plays the harp,
Beats a rock with a stick,
Becomes a priest at least,
A delicious demon.
Two men need one money one money needs no man,
One is on ones knees,
Loses ones head,
Except maybe a delicious demon,
Then one is no longer,
So delicious!
