Islam-o-nut

By Hubert van Ravesteyn (1671)

It looks like any other nut.

The outer shell is hard

And seemingly impervious,

The flesh within is poisoned.

Despite the strength of its integument

This is prone to burst-forth

After fermentation.

It will lay in a shrinking room,

Touching all within.

So this is a nut one must not crack

In the event its toxic traces

Spill over the table.
