I know the human being and the fish can coexist peacefully

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 says to the class, "I have a lollipop for the student who can tell me the name of the greatest man that ever lived." 

The new Jewish boy raises his hand and says, "I think Jesus Christ was the greatest man who ever lived."  "That's exactly the answer I was looking for" the teacher beamed, and gave him a lollipop.

During recess another Jewish boy asked him,  "why did you say Jesus Christ? "

The boy stops licking his lollipop and says,  "You know it's Moses,  and I know it's Moses, but business is business."
