Tonight’s new episode is titled “The Coma and the Oxford Comma.” I note it with particular glee, because my children once ridiculed me for drilling them at dinner about “the penultimate comma,” until one of them encountered it (and understood it) during an opening-day lecture at law school.  So there are reasons, after all, to be grateful for parents’ advice, information, and bad jokes. (Can you find the Oxford comma in that previous sentence?)
