XHH: There is an old biofakovsky story, I was told about my father. He lived at the student’s house, eating mice. To buy a student expensive, to breed reluctance, agreed to take on the department from those white that for experiments. Well, I put three pieces in a box and went to the dining room after studying. I put the box next to it, and the elbow and the butt. The mice fled. Students of the biofak - their own people, jumped from places and caught mice. and returned to the box. The Dozens. Because if mice are bred in the building, a second population inevitably arises.
