Erroneous Terminus

To Gaius Plinius Secundus, a short Poem on the Subject of Poisons

Tomatoes are not poisonous
Tomatoes do not poison us
Tomatoes are not poisonous
Tomatoes they would not.

Chillies are not poisonous
No chillies will not poison us
For chillies are not poisonous
It's just that they are hot.

Basil is not poisonous
And basil will not poison us
But scorpions might poison us
If there are a lot.

For scorpions are poisonous
And they might really poison us
If scorpions that are poisonous
Should breed under a pot.

But tomatoes are not poisonous
And they will never poison us
It is not even reasonous
That they should make us sick.

If you think that they are poisonous
And eating them will poison us
You have erroneous terminus
(or the wrong end) of the stick.
