The Opera Singer
A man went to Rome to study opera. At his first venue he sang his heart out and the audience shouted "Sing it again."
So he sang it again and the audience shouted "Sing it again." This happened once more with the audience shouting for him to sing it again.
By now the man was shattered so told the audience: "I'm sorry but I am tired and my voice is dry, I can't sing it again."
A voice from the audience shouted out: "Hey mate, you'll sing it again until you get it right."
