"John and Mary" was, I think, a routine by two incredibly talented people, Nichols and May. They worked together so well, their timing so precise, that people assumed them to be married but they weren't. In the John and Mary sketch, you, the audience was taken through a whole range of emotions and communications by each of them using only the inflection and rhythm of the other person's name. It was a tour de force. It was also very funny.
