Freshman year in college;first semester, the day before my US History mid-term exam.

I'd gone to class and read most of the material but had planned to cram during an "all-nighter" but ...

I had a bad toothache; went to the dentist who extracted all four wisdom teeth on the eve of the exam; he gave me strong pain pills which I took as I needed them.

Back in the dorm, my room mate asks if I want to try some home made moonshine (mixed with grape juice).

I tried it, liked it, drank a bunch, passed out, never studied.

I'v no recollection of taking the history exam, but I did, and a week later the professor called me into his office: he said I'd gotten the lowest grade in the class on the multiple choice, but the highest on the essay.

At that point I realized a career in the law awaited me.
