A Doggeral on a Dogma :

There is a place for negative thinking.
It's not always false alarm.
There is a place for negative thinking
Just before they drop the bomb.

PMA brought us formaldehyde
To insulate our walls,
And it also brought us DDT
To zap all that creeps and crawls.

It"s a kind of negative thinking
That's used to stop a war.
And when it's windy and cold outside
Negativity shuts the door.

Furthermore, many things are neutral,
And we need both yes and no,
So if yes... yes gets you pregnant,
Remember who told you so.

PMA brought us thalidomide
To put us all to sleep,
So when I caution let's think twice,
Don't just say I'm a negative creep.
