Three rabbis were talking over a regular Sunday morning breakfast get-together.
Rabbi Ginsberg says, "We have such a problem with mice at our schul. The shammos sets all kinds of baited traps but they kept coming back. Do either of you learned men know how I can get rid of these vermin?"

The second rabbi, 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 Shabbos after services were over a brilliant idea came into my mind.
The next Shabbos 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 bima.

Well, soon, hundreds of mice appeared on the bima and headed for the cheese.
While they were feasting on the cheese I Bar-mitzvahed all of them.
