Dating in 1960

It was a hot Saturday evening in the summer of 1960 and Fred had a date
with Peggy Sue. He arrived at her house and rang the bell.

"Oh, come on in!" Peggy Sue's mother said as she welcomed Fred in. "Have a
seat in the living room.  Would you like something to drink? Lemonade? Iced
tea?"

"Iced tea, please," Fred said. Mom brought the iced tea.
"So, what are you and Peggy planning to do tonight?" she asked.
"Oh, probably catch a movie, and then maybe grab a bite to eat at the malt
shop, maybe take a walk on the beach..."

"Peggy likes to screw, you know," Mom informed him.

"Uh...really?" Fred replied, with raised eyebrows.

"Oh, yes!" the mother continued. "When she goes out with her friends,
that's all they do!"

"Is that so?" asked Fred, incredulous.

"Yes," said the mother. "As a matter of fact, she'd screw all night if  we
let her!"
"Well, thanks for the tip," Fred said as he began thinking about alternate
plans for the evening.

A moment later, Peggy Sue came down the stairs looking pretty as a picture
wearing a pink blouse and full circle skirt, and with her hair tied back in
a bouncy ponytail. She greeted Fred.

"Have fun, kids," the mother said as they left.

Half an hour later, a completely disheveled Peggy Sue burst into the house
and slammed the front door behind her.

""The Twist, Mom!" she angrily yelled at her mother.
""The  damned dance  is called the TWIST!"
