"Hebrew School" joke

At the Henry Street Hebrew School, Goldblatt, the new teacher, finished the day's lesson. It was now time for the usual question period.

"Mr. Goldblatt," announced little Joey, "there's somethin' I can't figger out."

"What's that Joey?" asked Goldblatt.

"Well accordin' to the Bible, the Children of Israel crossed the Red Sea, right?"

"Right."

"An' the Children of Israel beat up the Phillistines, right?"

"Er--right."

"An' the Children of Israel built the Temple, right?"

"Again you're right."

"An' the Children of Israel fought the' gyptians, an' the Children of Israel fought the Romans, an' the Children of Israel wuz always doin' somethin' important, right?"

"All that is right, too," agreed Goldblatt. "So what's your question?"

"What I wanna know is this," demanded Joey. "What wuz all the grown-ups doin?"
