It was 1957. Mike goes to pick up his date, Molly.
Molly’s father Samuel opens the door and invites him in.
He asks to Mike what they’re planning to do on the date.
Mike politely responds that they’ll probably just go to the malt shop or to a drive-in movie.
Molly’s father suggests, “Why don’t you kids go out and screw? I hear all of the kids are doing it.”
Mike was bewildered. “Excuse me, sir?”
“Oh yes, Molly really likes to screw. She’ll screw all night if we let her.”
Molly comes downstairs and announces that she’s ready to go.
About 15 minutes later, a thoroughly disheveled Molly rushes back into the house, slams the door behind her, and shouts at her father, “Dad! The Twist! It’s called the Twist!”
