     ♦ "...Бывало, по целым часам [от Печорина] слова не добьешься, зато уж иногда как начнет рассказывать, так животики надорвешь со смеха" (Лермонтов 1). "...Sometimes you couldn't get a word out of him [Pechorin] for hours on end, but when he occasionally did start telling stories you'd split your sides laughing" (1b).
