Three Rabbis were talking over a regular Sunday morning breakfast get-together.
Rabbi Ginsberg said, "We have such a problem with mice at our shul. The shammos sets all kinds of baited traps but they keep coming back. Do either of you learned men know how I can get rid of these vermin?"
The second Rabbi Cohen replied, "We have the same problem at our synagogue. We've spent all kinds of gelt on exterminators, but the problem still persists. Any suggestions?"
The third Rabbi, Rabbi Slosberg, looked at Rabbi Ginsberg and Rabbi Cohen, and told the following story:
"Rabbis, we had the same problem with mice at our synagogue. We tried traps, exterminators, even prayers; but nothing worked. Then one Shabbat, I went to the synagogue about an hour before services started. I brought a big wheel of yellow cheese and placed it in the center of the bimah. Well, soon hundreds of mice appeared on the bima and headed for the cheese. While they were feasting on the cheese, I Bar Mitzvah'ed all of them. I've never seen any of them in shul again."
