Mulla
Nasrudin's face lit up as he recognized the man who was walking ahead of him
down the subway stairs. He slapped the man so heartily on the back that the man
nearly collapsed, and cried, "Goldberg, I hardly recognized you! Why, you
have gained thirty pounds since I saw you last. And you have had your nose fixed,
and I swear you are about two feet taller."
The man looked
at him angrily. "I beg your pardon," he said in icy tones, "but
I do not happen to be Goldberg."
"Aha!"
said Mulla Nasrudin, "so you have even changed your name?"
