Prof. Mark Liberman (Language Log) has all about this “exchange” — in this instance, a literal fistfight rather than a figurative one — all about whether to “elevate the status of Russian to a second language, equal to Ukrainian, in about half the regions of the country, including Kiev.” You have to see the picture, or at least the video (which I’m deliberately withholding so that more people can visit and maybe see what a great site Language Log is).
