it is not possible

to steal a diamond

without its aid

logically we’ll need

not only a plan

and a cat costume

but also something

to cut out a hole

in the glass display guarding the diamond

so that we could grab it

in the night

and so

it is merely impossible

to steal a diamond

without already having

at least one

as they say

in thieves’ cant:

chunk o’ gin fancies a rounder

or:

no diamond

no fun
