"One might be tempted to pair alcohol with subject matter — Jameson and Joyce, say; or champers and Fitzgerald — but don’t get cute. The generally accepted formula is: P/D = 1. The "P" refers to proof (of the alcohol). The "D" is your specific dislike of this particular group of students on a scale of 1 to 100, with 100 being total unmitigated rage. For groups exceeding 100, a Bacardi 151 floater is acceptable."
