An old 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 to answer the phone.  His wife could hear him say, "Hello?" Then he said, "Sure is." Then he hung up the receiver 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?" and then he said, "Sure is." And 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 then asked, "Well, what did the person say?"  

He said, "It's odd, a woman just keeps saying, 'Long distance from Chicago..'"
