A Yom Kippur Joke

I heard the following joke from a friend and professor of comparative literature, Nauman Naqvi, who heard it from a friend, Gil Anidjar, who was a student of Derrida's. It goes as follows:

On Yom Kippur Eve the Rabbi of the congregation went up before the ark, bowed low, and said in a whisper, "I am nothing before you, O God." Whereupon he wept and returned to his place on the bimah. Then, the chazan went up to take his turn before the presence of the Holy One. He too, bowed low and uttered the words, "I am nothing before you, O God." And he too, wept and returned to his place on the Bimah. Then, the lowliest member of the congregation, who made his living as synagogue janitor, went up to ark to bow low. But as he did, saying, "I am nothing before you, O God," the Rabbi turned the chazan and gave him a little nudge, saying, "Look who feels like nothing tonight."
