it's an awesome bit of stereotyping too. i bet they also, um, eat borscht! and really like nesting dolls! and have, um, uncles or some other obscure relatives who are former kgb/oil oligarchs/alcoholics who like vodka.
I thought it was obnoxious and it really pissed me off. One of the things I like best about watching these things live (via app) is the lack of commentary. I really can't stand those effers.
