Speaking of grain alcohol ...
Freshman year in college: a Yankee in The South.
First mid-terms of the year.
The day before my US History exam I developed a horrible toothache: went to the dentist and he extracted four impacted wisdom teeth and gave me strong pain pills.
Back at the dorm my room mate, a guy from "the hills" rolled in with some moonshine his buddy had made and asked if I wanted some?
I did: my first "mountain dew:" he mixed / cut it with grape juice, called it "PJ."
Tasted good, I liked it and apparently drank quite a bit.
The combination of the pain pills and the strong liquor was ... profound.
I awoke the following AM in a deep fog, stumbled in wholly unprepared to take the exam (barely made it in time) but I took it.
The lack of studying coupled to the deep stupor from the booze and drugs permeated my mind to a redolent degree: it was all a haze.
A week later the prof called me into his office: he said I had the LOWEST grade in the class on the multiple choice section and the HIGHEST on the essay.
I explained what happened.
A few years later I asked him to write a recommendation so I could attend law school: not sure what he said but it worked.
