Billy & Jerry - A (Brief) Conversation

    Billy sits on his couch.  Jerry calls.  Billy answers.
    "Hello."
    "What are you doing?"
    "Who is this?"
    "It's Jerry."
    "Oh."
    "What are you doing?"
    "I'm watching Back to the Future Part II."
    "What?"
    "I'm watching Back to the Future Part II."
    Jerry doesn't say anything for a long time.  And then, "I'm coming over."
    Billy says, "Ok."
    Jerry comes over.
