"Come on, then. At least I'll show you the carps there." And as they went, my dad already had a premonition, that this might be it. It was a familiar infallible inkling, that told him up front where to sell a refrigerator, where to sell a vacuum and where it was useless even to ring a bell. Just as he could feel a good business, so he now felt this as his chosen pond and in it - chunky carps. They stopped at the dam and doctor Václavík let him take in the view. Dad sighed and doctor Václavík, his friend, said profoundly: "And now about the carps." He pulled out a bun, broke it in half and threw a half towards the dam. The doctor smiled with certainty and dad kept his gaze on the bun. Suddenly the surface broke, an enormous yellow shape appeared and an enormous hole went clap! And the bun was gone. Dad cried out: "For heaven's sake, that one must weigh at least eleven pounds."And the doctor said solemnly: "Thirteen."
