The mural
Every newspaper in New York sent a reporter and a staff photographer to the office of a local ophthalmologist when it was learned that he recently performed a successful sight- saving operation on the wife of the country's most celebrated mural artist, who, in addition to paying the doctor's usual fee, had gratefully insisted on painting one of his contemporary masterpieces across an entire wall of the doctor's waiting room.
The mural turned out to be an immense multicolored picture of a human eye, in the center of which stood a perfect miniature likeness of the good doctor himself.
While cameras clicked and most of the newsmen crowded around the famous artist for his comments, one cub reporter drew the eye specialist aside and asked:
"Tell me, if you can, Doctor-what was your first reaction on seeing this fantastic artistic achievement covering an entire wall of your office?"
"To tell the truth," the physician replied, "my first thought was, thank goodness I'm not a hemorrhoid specialist!"
