In my family, I’m the first eminent ancestor

From A Treasury of Jewish Folklore by Nathan Ausubel.

Stale Ancestors — Stale Learning

Usually the orthodox rabbis of Europe boasted distinguished rabbinical genealogies, but Rabbi Yechiel of Ostrowce was an exception. He was the son of a simple baker and he inherited some of the forthright qualities of a man of the people.

Once, when a number of rabbis had gathered at some festivity, each began to boast of his eminent rabbinical ancestors. When Rabbi Yechiel’s turn came, he replied gravely, “In my family, I’m the first eminent ancestor.”

His colleagues were shocked by this piece of impudence, but said nothing. Immediately after, the rabbis began to expound Torah. Each one was asked to hold forth on a test culled from the sayings of one of his distinguished rabbinical ancestors.

One after another the rabbis delivered their learned dissertations. At last it came time for Rabbi Yechiel to say something. He arose and said, “My masters, my father was a baker. He taught me that only fresh bread was appetizing and that I must avoid the stale. This can also apply to learning.”

And with that Rabbi Yechiel sat down.
