In a burning stove with all of the doors and windows sealed for freshness like they did at Auschwitz ?
Naa, you're thinking of truck exhaust and Zyklon-B. I'm talking about that special (magical even) kind of clean coal that Dump somehow enabled by ending that whole war on coal thing.
I'd like to think your scenario wouldn't matter much to Dump himself though. From what I've been seeing these last several years, I don't think his brain gets much oxygen to begin with. That bloated, flabby, vaguely feminine body of his has been fortified with pills and the chemicals and preservatives of junk food, long term. He'd just pretend he's savoring his own farts again, maybe wonder out loud why people are coughing and gasping for breath. Hicks get off the floor and steam me.
