It was during the cold war. The fate of the Western world hung in the balance. A secret agent had to find a spy named Epstein in New York and give him a secret code.


So, the agent entered the lobby of the apartment building on the lower east side of Manhattan where he lived and browsed the directory. He noticed there were 2 Epsteins listed; one on the 1st floor, the other on the 2nd.


He knocks on the door of the Epstein on the first floor. When Epstein opens the door, the agent tells him, The sky above, the mud below.


Mr. Epstein replies, Oh! You want Epstein the spy. Second floor.
