Hodja Mullah Nasruddin: the mother in law

People ran to tell the Mullah that his mother-in-law had fallen into the river. “She will be swept out to sea, for the torrent is very fast here,” they cried.
Without a moment’s hesitation Nasrudin dived into the river and started to swim upstream.
“No!” they cried, “DOWNSTREAM! That is the only way a person can be carried away from here.” “Listen!” panted the Mullah, “I know my wife’s mother. If everyone else is swept downstream, the place to look for HER is upstream.”
