He seemed to be half drunk. Besides the rat comments, he seemed pretty all over the place. Talking about Russia and Chechens and shit makes 0 sense since Khabib is very much loved in Russia because of his lack of political involvement.
If I was Khabib, I would've made a comment about how people under stress drink and he's chugging his whiskey like its a bottle of water. Would've shut him up about his damn whiskey.
