Although he always odered just ham and eggs everyday,
one customer at the diner always studied the menu care-
fully each day before ordering.
One day his regular waitress decided to see if he could
be made to order anything else. Before giving him the
menu she marked out the ham and eggs entry.
After waiting a few minutes she asked, "Did you notice,
sir, that I scratched something that you like?"
Without looking up from the menu, he replied, "So go wash
your hands and bring me some ham and eggs."
