Piety Jokes

It is Yom Kippur, the holiest day of the Jewish calendar. As the day draws
to a close, in a small synagogue in Vilna, the rabbi is praying
fervently. "Oh, God," he says, "I am nothing before you!" The cantor
also says, "Oh, God, I am nothing before you!" Then the shammes,(*)
inspired by their piety, cries out, "Oh, God, I am nothing before
you!" The cantor raises his eyebrows, looks at the rabbi, and says,
"Nu, look who thinks he's nothing!"
(*)shammes: beadle, responsible for maintaining the synagogue, ushering, etc.
