An elderly couple was just settling in to bed one night when the phone rang.
The husband got out of bed and went into the living room (parlor) to answer the phone.
His wife could hear him say, "Hello?" Then he said, "Sure is." He hung up the receiver (remember those) and went back to bed.
A minute later the phone rang again. The husband got out of bed and went into the other room and his wife could hear him say, "Hello?" again and then he said, "Sure is." again. He hung up the receiver and went back to bed.
The wife asked who it was. The man said he didn't know.

The wife asked again about the caller. The man said he didn't know who it was.
The wife then asked, "Well, what did the person say?
He said, "It's odd, a woman just keeps saying, "Long distance from Chicago."
