Sense Sonnet - Acher

Test Result

There was this monkey in a cage;
And if he wanted some cocaine,
He'd push a button on a gauge,
For a measured amount - with pain.
Each time he'd press the button in,
He would receive a double hit.
A bag would drop into a bin;
A low volt shock would sting a bit.
One day, the voltage was increased,
And no bags dropped in this new test.
All other activity ceased.
The monkey pressed and pressed and pressed...

I know the hell cocaine can be.
It made a monkey out of me.
