"Basement Dwells..?" (Entry 219)

If there'd been a ghost,
We'd have kept it in the basement.
In the cupboard in the corner,
Behind the padlocked paint-peeled door.
It would scratch and howl and rattle his chains,
Wanting to scare his only joy.
If there'd been a ghost,
We'd have kept it in the basement.
If there'd been a basement at all.
