"Ad Diem" is a word in LAW AND LEGAL

A grizzled old man was eating in a truck stop when three Hell's Angels' bikers walked in. The first walked up to the old man, pushed his cigarette into the old man's pie and then took a seat at the counter. The second walked up to the old man, spat into the old man's milk and then he too took a seat at the counter. The third walked up to the old man, turned over the old man's plate, and then he took a seat at the counter. Without a word of protest, the old man quietly left the diner. Shortly thereafter, one of the bikers said to the waitress, "Humph, not much of a man, was he?" The waitress replied, "Not much of a truck driver either, he just backed his big-rig over three motorcycles."
