On this day in 1872, Emily Post was born. Then she gave a bunch of people some good tips on how not to slurp your soup, and then in the '60s she passed away. All of Post's descendants seemed to have also successfully dabbled in etiquette careers. Above, she narrates a 1947 instructional video on table manners, and here is a cheeky little advice column wherein she advises teenage ladies to be pimps, too, go on, brush your shoulders off, except in nice flowery old-timey language.

Have a nice, polite Saturday night!
