It's the spring of 1957 and Bobby goes to pick up his date, Peggy Sue. Bobby's a pretty hip guy with his own car and a ducktail hairdo. At the front door Peggy Sue's father answers and invites him in.
"Peggy Sue's not ready yet, so why don't you have a seat?" he says.
"That's cool." says Bobby.
Peggy Sue's father asks Bobby what they are planning to do. Bobby replies politely that they will probably just go to the malt shop or to a drive-in movie.
Peggy Sue's father responds, "Why don't you kids go out and screw? I hear all of the kids are doing it."
Naturally this comes as quite a surprise to Bobby and he says, "Whaaaat?"
"Yeah," says Peggy Sue's father, "Peggy Sue really likes to screw; she'll screw all night if we let her!"
Bobby's eyes light up and he smiles from ear to ear as he mentally revises the night's plans. A few minutes later, Peggy Sue comes downstairs in her little poodle skirt with her saddle shoes and announces that she's ready to go. Almost breathless with anticipation, Bobby escorts his date out the front door while Dad is saying, "Have a good evening, kids!"
About 20 minutes later, a thoroughly disheveled Peggy Sue rushes back into the house, slams the door behind her and screams at her father: "Dammit, Daddy! The twist! It's called the twist!!"
