A young man asks the rabbi about who is truly a wise man.
The rabbi says:
"Any dummy can be right 50% of the time. A wise man is right
60% of the time. Rabbi Rosenberg from Bialystok was right 75%
of the time. However, if someone is right 90% of the time,
it is very suspicious, and if someone is right 100% of the
time, he must be a bad, violent criminal man, and you should
avoid him like a plague".
