although some rabeim had interesting ways of disciplining
Reminds me of the line that formed every week by the rabbis desk, for the kids that didn't know the Rashi, we where slapped in the face 2-10 times. And the time I took out of the garbage a paper the rebbi had thrown out ,I was put on his desk, and got 30 slaps in my face.
When my father called the principal to complain he said we should understand him as he's going through hard times in sholom bayis.
