It’s 1957 and Bob goes to pick up his date, Peggy Sue. Peggy Sue’s father answers the door and invites him in. He asks Bob what they’re planning to do on the date.

Bob politely responds that they’ll probably just go to the malt shop or to a drive-in movie.
Peggy Sue’s father suggests, “Why don’t you kids go out and scrw?

“Excuse me, sir?” “Oh yes, Peggy Sue really likes this. She’ll do this all night if we let her.”
Peggy Sue comes downstairs and announces that she’s ready to go. About 20 minutes later, a thoroughly disheveled Peggy Sue rushes back into the house, slams the door behind her, and screams at her father,
“Dad! The Twist! It’s called the Twist!”
