   • 1999, Andrey Grachov, Ярый против видеопиратов:

     Легко́ отде́лался, па́дла… — заду́мчиво сказа́л Артём, сра́зу помрачне́в, — е́сли бы он мне попа́лся, чмо пога́ное, я бы ему́ так бы́стро не дал умере́ть.

     Lexkó otdélalsja, pádla… — zadúmčivo skazál Artjóm, srázu pomračnév, — jésli by on mne popálsja, čmo pogánoje, ja by jemú tak býstro ne dal umerétʹ.

     "He got off easy, the wretch," Artyom said pensively, immediately turning gloomy. "If I had got my hands on that rotten sonofabitch, I wouldn't have let him die so quickly."
