The Chofetz Chaim Passes Around A Petition
There was a town near Radin whose Mikva fell into disrepair and could no longer function as a kosher mikva.  The Chofetz Chaim, then at a very advanced age, wrote a letter to the community leader urging them to raise money for the important cause.  His words fell on deaf ears as the townspeople cried poverty.

After a number of appeals failed, the Chofetz Chaim, despite his frail health, personally traveled to the town and called a meeting in the Shul.  He told the people that he is very old and does not know how many more years he has left on earth.  But when it comes to an end he will stand before the Bais Din Shel Ma'ala and need to account for all his actions.  They will ask him, "Yisroel Meir what did you do about the town near Radin that did not have a functioning mikva.  How can you let a Jewish community be without such an important and central need?"

To this I will respond said the Chofetz Chaim that I appealed to them many times but my words fell on deaf ears.  What more could I have done?  Therefore, said the aged tzaddik, I am passing around a form for everyone to sign that attests to the truth of my words.  I need to take this with me to show them.

Needless to say the speech had its intended effect and the mikva was repaired.  (Rav Pam on Chumash)
