The Impossible Astronaut
(A telephone is ringing in the Oval Office, and a man has run to answer it.)
NIXON: Hello? Hello, this is the President. (crackles) Hello, this is the President of the United States. Who is this? Is it you again?
CHILD [OC]: Look behind you.
NIXON: How did you get this number? This is my private line. How did you get through?
CHILD [OC]: They're everwhere, all the time. We see them every day, but you have to look behind you.
(Nixon's infamous tape recorder catches all this.)
NIXON: There is nothing behind me. How did you get this number?
CHILD [OC]: The spaceman told me.
NIXON: What spaceman?
CHILD [OC]: It doesn't matter. I'm telling you about monsters. Please, you must look behind you.
NIXON: Young lady, there are no monsters in the Oval Office.
(Telephone call ends. The President leans back in his chair to reveal a Silent standing there.)
