An author of a ספר brought it to רבי אייזל חריף to request his הסכמה. He placed it on the open גמרא from which the רבי had been learning and asked him to look at it. After doing so and seeing that it was worthless, the רבי told him “I suggest that you leave here quickly, before the רבנית comes and hands you over for שחיטה.” “What do you mean for שחיטה?” he asked. רבי אייזל חריף responded: “A chicken once passed over the גמרא and dirtied it. When my wife saw this, she quickly took the chicken for שחיטה.“
