甄宇，北海人，建武中，为青州从事，徵拜博士。每腊，诏书赐博士羊，人一头，羊有大小肥瘦。时博士祭酒议欲杀羊，称分其肉。宇曰：“不可。”又欲投钩，复耻之。宇因先自取其最瘦者，由是不复有争讼。后召会，诏问瘦羊甄博士，京师因以号之。 |
| | Zhen Yu was a native of Bohai. In the middle of Jianwu era, he served as an official in Qingzhou and was later summoned to be appointed as a Doctor (of Literature). Every winter, the imperial edict granted each doctor one sheep; however, these sheep varied in size and fatness. At that time, the head of the doctors proposed to slaughter the sheep and divide its meat among them. Yu said, "That is not acceptable." They then wanted to draw lots with hooks, but were again ashamed. Yu therefore took the skinniest sheep first, and thus there was no further dispute. Later, when summoned to court, the emperor asked about Doctor Zhen of the skinny sheep, and this nickname became known in the capital.
