Geologiya professori V.V. Dobrovolskiy dala amaliyotida talabalarga shunday degan edi: "Har bir Bilimli Talaba Papiros Chekishi Kerak" (ruscha: Kazhdyy Obrazovannyy Student Dolzhen Kurit' Papirosy), keyin diqqat bilan tinglayotgan nevarasiga qarab qo‘shib qo‘ydi: "Sen, Yura, Kichiksan. Biroz Kut, Inson" (ruscha: Ty, Yura, Mal. Podozhdi Nemnogo, Chelovek). Endi ayting-chi, nima uchun professor to‘satdan chekishning bunday ashaddiy targ‘ibotchisiga aylanib qoldi?
