This story is good, But
"By the way, that student was EINSTEIN." this is not true.
This is typical of the urban myth genre and can not actually be regarded as a real conversation between Albert and his former teacher or university professor. Einstein admitted to being a mediocre student and did not become famous until quite some time after finishing his studies. How likely is it that a former teacher would so accurately remember a short conversation that took place decades earler with an undistinguished student? Moreover, in his Autobiographical Notes, Einstein stated that his "deep religiosity" as a Jewish child ended at the age of 12 when he developed a sceptical attitude towards God.
Anyways this is good, story.
