Last night, my ten year-old and I watched an enriching documentary full of experts in the field, analysis of the data on the topic, and even some live scientific experiments to demonstrate the conclusions of the research. It's Netflix's "History of Swear Words." It's a series, and the first episode centered on the word "fuck," the second, on the word "shit." That's as far as we've gotten so far. Nicolas Cage is the host, in a tux, sitting in a library complete with a booze globe and leather chair. Linguistic experts, actors and comedians (Sarah Silverman, Isiah Whilock Jr., Nikki Glaser, Nick Offerman, London Hughes, Patti Harrison, +), and professional orators are interviewed.
