"And you say you have the same nightmare every night," the doctor
inquired. "What is it?"
The suffering man answered:
"I dream that I'm married."
"Ah, hum!" the physician grunted perfunctorily. "To whom?"
"To my wife," the patient explained. "That's what makes it a
nightmare."
The inn-keeper was inclined to take advantage of a particular guest who
did not scrutinize the bills rendered. When the clerk mentioned the fact
that this guest had complained of a nightmare, the host brightened, and
marked down an item of ten dollars charge for livery.
