Outside, on a busy street in Riverdale. Inside, the Davis Aerobics Center for Good Health. Jack Davis is taking Richard's blood pressure.
Jack:	OK, Richard. That's terrific. Your pressure is 120 over 75, and that's fine. Now stand up, please. [Richard stands up, and Jack takes his blood pressure again.] Good, it's 122 over 80. You can sit down now. When was your last complete physical?
Richard:	[He thinks.] Six months ago.
Jack:	Good. Do you have any back or knee problems?
Richard:	Nope. I am in perfect health.
Jack:	What do you do for a living, Mr. Stewart?
Richard:	I'm a photographer.
Jack:	Interesting. What do you photograph?
Richard:	Everything. The American scene. People, places, events.
Jack:	Did you ever think of photographing an aerobics class?
Richard:	No. ... I can't remember taking pictures of people exercising.
Jack:	But don't you think it'd be a good subject?
Richard:	Sure.
Jack:	I need some good photos for my advertising, Mr. Stewart. Maybe you can photograph a class, and I can give you and Mrs. Stewart a month of classes—free.
Richard:	When can I photograph a class?
Jack:	Anytime.
Richard:	How about today?
Jack:	Terrific!

In Richard and Marilyn's room later that day. Marilyn is alone, waiting for Richard. She is folding some towels. Richard sings and dances into the room.
Marilyn:	Richard, did you go to the Davis Aerobics class today?
Richard:	[He takes off his camera and film bags and dances around the room.] Yes, I went to the aerobics class today.
Marilyn:	What is wrong with you?
Richard:	Nothing. I am in excellent health. [He starts dancing with Marilyn.] I have ideal blood pressure. A perfect heart. In others words, I'm in wonderful condition.
Marilyn:	Richard, did you go to the aerobics class, really?
Richard:	Don't forget to invite Susan for dinner.
Marilyn:	[not paying attention] And your legs don't hurt?
Richard:	[He jumps up and down.] Hurt? What do you mean?
Marilyn:	What about your arms? Lift your arms up like this. [She lifts up her arms to show him, and he lifts his arms.] And they don't hurt—not even a little?
Richard:	Nope.
Marilyn:	You are in great condition. I can't believe it!
