John, John, John and John

The office phone rang and the voice at the other end asked, "May I speak to Mr John?"

"Mr John is not in his seat."

"In that case can I speak to the other Mr John?"

"The other Mr John is out of station."

"Then put me on to the third Mr John."

"Sorry, the third Mr John has gone out for lunch."

"Okay then, I will speak to the last Mr John."

"John speaking."
