The Scientific Jerk

This is clearly unhealthy.
I mean he stands straight and tall with his hands behind his back. And anybody who sees him would think of him as a nice guy or a great scientist. Then he would open his mouth. And the words that spill out of him would break you into pieces. He'd never say bad words or cuss at anyone, it's just the things he says. They feel like a knife scratching on glass right inside your ears. What a jerk!
