The Merv host who refused recognition
A man from Merv was often lavishly hosted by an Iraqi friend and kept urging him to visit Merv so he could return the favour. When the Iraqi finally arrived, the Merv man pretended not to know him, and as the guest removed his turban, then his cloak, to be recognized, the host said that even if he stepped out of his skin he would not know him. The joke shows that reciprocity promised at a distance costs nothing, and that the miser escapes the debt by refusing to admit the relationship exists.
