At Caltech there was a Fraternity based out of Dabney House. Caltech food services back in the day made a special food item that was only served to the Dabney House, and the term "Dabney Eats It" was born, or just DEI. Graduates of Caltech have been known to place the DEI letters on all sorts of things, Legend has it more than a few circuit boards in the Apollo Lunar Landers have a DEI etched onto them in an unused spot, meaning DEI has even reached the Moon! I wonder if the Diversity Equity Inclusion crap is just another attempt by a Caltech grad to spread the legend of DEI?
Watch the movie "Real Genius", starring a young Val Kilmer and the gorgeous Deborah Foreman. Set at Cal Tech, DEI makes numerous "guest starring" appearances in the background. And of course the scene that made me fall in lust with Ms. Foreman!
