Once Rabbi Beroka asked Elijah,"Is there anyone in this marketplace who has a place in the world to come?"
Two men walked by.
Ellijah remarked "These two have a share in the World to Come."
Rabbi Beroka asked them "What is your occupation?"
They replied,"We are comedians. When we see people who are depressed we cheer them up,also when we see two people quarreling,we strive hard to make peace between them."
(Babylonian Talmud, Ta'anit,22a)
