I just love this joke! You really must read it!
The ending is darkened to prevent spoiling - just select it to make it visible.

It's the Spring of 1957 and Bobby 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.

"Carrie's not ready yet, so why don't you have a seat?" he asks.

"That's cool," says Bobby.

Carrie's father asks Bobby what they're planning to do. Bobby
replies politely that they will probably just go to the soda shop
or a movie. Carrie's father responds, "Why don't you two go out
and screw? I hear all the kids are doing it."

Naturally, this comes as a quite a surprise to Bobby, so he asks
Carrie's Dad to repeat it. "Yeah," says Carries father, "Carrie
really likes to screw, she'll screw all night if we let her!"

Well, this just made Bobby's eyes light up, and immediately
revised his plans for the evening. A few minutes later, Carrie
comes downstairs in her little poodle skirt and announces that
she's ready to go. Almost breathless with anticipation, Bobby
escorts his date out the front door.

About 20 minutes later, a thoroughly disheveled Carrie rushes
back into the house, slams the door behind her, and screams at
her father: "DAMMIT, DADDY! THE TWIST!! IT'S CALLED THE TWIST!!!"
