Anyway there's smoke. Gray,

Mostly. Sometimes blue or black,

Depending of course on what's burning -

A leaf, a mountain, a country or a corpse!

Puff balls (silly things) make smoke without a fire

You've seen them - round, brown, and brittle -

The elderly metamorphosis of a mushroom,

Of which less said the better

Because of fission (you remember)

Spewing the final idiocy - and smoke.

Enough of it - had you noticed? -

Will bar the sun.
