An Afghanistan diplomat visiting the US for the first time was being
wined and dined by the State Department. The diplomat was not used to
the salt in American foods (French fries, cheeses, salami, anchovies,
etc.) and was constantly sending his manservant Abdul to fetch him a
glass of water.

Time and again, Abdul would scamper off and return with a glass of
water, but then came the time when he returned empty handed.
"Abdul, you son of an ugly camel, where is my water?" demanded the diplomat.

"A thousand pardons, O Illustrious One,"
stammered the wretched Abdul,
"But a man is sitting on the well!"
