R. Micha Berger tells the following story about R. David Lifschitz as part of a great post (link):
YU required written finals. I think Rav Dovid once told me that he wouldn’t have given them otherwise. In any case, the morning of the final, rebbe would ask us two questions that echo Rav Shimon’s “faher“:
First, he would want to know who had eight hours of sleep the previous night.
Second, he would ask who had breakfast that morning.

Those who didn’t get a full night’s sleep were sent back to bed. Those who skipped breakfast were given $5 and sent to the cafeteria. (At least, those who addmitted to it. Few people would raise their hands the second time around, and I know for sure at least some of us were just avoiding taking rebbe’s money…)
