"A young Jewish boy starts" joke

A young Jewish boy starts attending public school in a small town. The teacher
of the one-room school decides to use her position to try to influence the
new student. She asks the class, "Who was the greatest man that ever lived?"
A girl raises her hand and says, "I think George Washington was the greatest
man that ever lived because he is the Father of our country." The teacher
replies, "Well...that's a good answer, but that's not the answer I am looking
for." Another young student raises his hand and says, "I think Abraham
Lincoln was the greatest man that lived because he freed the slaves and helped
end the civil war."... "Well, that's another good answer, but that is not
the one I was looking for." Then the new Jewish boy raises his hand and
says, "I think Jesus Christ was the greatest man that ever lived." The
teacher's mouth drops open in astonishment. "Yes!", she says, that's the
answer I was looking for." She then brings him up to the front of the
classroom and gives him a lollipop. Later, during recess, another Jewish boy
approaches him as he is licking his lollipop. He says "Why did you say,
'Jesus Christ'?" The boy stops licking his lollipop and replies, "I know
it's Moses, and YOU know it's Moses, but business is business."
