(From the pilot episode. Kevin and his friend Paul are in Kevin's bedroom reading his older sister Karen's sex education book Our Bodies, Ourselves
. Actually, the book didn't come out until 1971, while this episode was set in 1968!)
NARRATOR (originally voiced by Arye Gross, later replaced by Daniel Stern): This was it. The last night of summer.
PAUL (Josh Saviano): Holy cow!
KEVIN (Fred Savage): Try not to drool on it, OK? If Karen finds out I have this, she'll kill me.
NARRATOR: Paul and I decided that the best way to prepare for junior high school girls was to look at them naked.
(Sound of a knock on the door. Shot of the door as Kevin's mother Norma opens it and looks in. Shot of Kevin and Paul looking at Norma off-screen with surprise, as Paul tries to hide the book by sitting on it. Close shot of Norma looking at them off-screen.)
NORMA (Alley Mills): Paul, your mother called. She wants you to come home right away.
PAUL: Well, I guess I'll see you at bus-stop.
PAUL: Last night I had a dream that...when I got to school I realized I had no clothes on.
KEVIN: If you're naked when you get to the bus-stop, I'll tell ya.
PAUL: Do you know what you're gonna wear?
KEVIN: Paul, I have no idea.
NARRATOR: Actually, I'd been planning my wardrobe for about six weeks.
