Chubby Checker says...

It's the summer of 1957 and Bobby goes to pick up his date, Peggy Sue.
Bobby's a pretty hip guy with his own car and a duck tail hairdo. When
he goes to 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."

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, "we know that Peggy Sue really likes
to screw, why she'd screw all night if we let her!"

Bobby's eyes light up and smiles from ear to ear. Immediately, he has
revised the plans for the evening. 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," with a small wink for Bobby.

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 !!!!!!!!"
