 CONT: When Nick is in the psychiatrists office the doctor is  holding a pen in her right hand and is also holding the phone in the  same hand. Then Nick tells her to guess a number and she does, and  he repeats it back to her and she is amazed and hangs up the phone  and throws the pen down on the floor. She then grabs the arm of the  chair with the now empty hand. In the very next shot she has the pen  in her hand again and throws it down again.
