Earth is not room enough

Locked in a room, strapped to a hollow chair,
Faint musty smell, odour of stale air,
Sealed from the outside in a cage that is six-foot square,
Eyes that are fixed in a glazed, disbelieving stare.

Cyanide pills dropped in an acid bath,
Froth forms a cloud as deadly as death's own staff,
Lungs start to burst trying to hold your breath,
But have the last laugh 'cos Earth is just a cage seven thousand miles wide!
