Measured emotional response

Doctor Odd was a master of measurement, knowing every unit of measurement there was.
Except emotions.
He could not measure emotions.
There was no emotional yardstick.
There was no emotional scale.
There was no emotional multimeter.
“I must invent one,” he said.
So, over the years, he ran countless experiments.
Taking candy from babies.
Showering people with love.
Telling parents their children had died at war.
Giving gifts to orphans.
And running lunatics through a maze of unfamiliar lights and sounds.
Not that any ethical scientist would respect his results, he revealed his horrific findings:
“I have no emotions whatsoever.”
