It's the Spring of 1957 and Lewis goes to pick up his date. He's a pretty hip guy with his own car. When he goes to the front door, the girl's father answers and invites him in. "Mary Jane's not ready yet, so why don't you have a seat?," he says. "That's cool" says Lewis.
Mary Jane's father asks Lewis what they're planning to do. Lewis replies politely that they will probably just go to the soda shop or a movie.
Mary Jane's father responds "why don't you two go out and screw? I hear all the cool kids are doing it."
Naturally, this comes as a quite a surprise to Lewis - so he asks Mary Jane's Dad to repeat it. "Yeah," says Mary Jane's father, "Mary Jane really likes to screw; she'll screw all night if we let her!"
Well, this just made Lewis' eyes light up, and his plan for the evening was beginning to look pretty good. A few minutes later, Mary Jane comes downstairs in her little poodle skirt and announces that she's ready to go. Almost breathless with anticipation, Lewis escorts his date out the front door.
About 20 minutes later, Mary Jane rushes back into the house, slams the door behind her, and screams at her father:
"Dammit Daddy! It's called the TWIST!"
