I include an offering for your humour page, from

A group of Jews were at early morning prayers in synagogue.

The rabbi suddenly stands up and declaims, “Oh Lord… I am nothing!” and sits down again.

A little while later, the synagogue’s cantor stands up and he says, “Oh Lord, I am nothing!”

Everyone continues praying. Then the synagogue’s janitor gets together his courage, and he jumps up and says, “Oh Lord, I am nothing!”

So the rabbi leans over to the cantor and whispers, “Now look who thinks he’s nothing!”
