Saw this online and I laughed out loud:
All Jews, regardless of their belief or disbelief, pray the same prayer, only with a different dialect. The traditional Jew prays, "Shema Yisrael, Adonai Eloheinu, Adonai Echad." Not to be outdone, the atheist Jew prays, "Shema Yisrael, I deny Eloheinu, I deny Echad." And the agnostic Jew recites, "Shema Yisrael, I dunno Eloheino, I dunno Echad."
