I think you're unclear on the concept.

Early 1970s: the “Sexual Revolution” was all the rage. And a young generation of college students thought that they, and they alone, had invented sex.

In the theater department of a Midwestern university, a student-written play was being produced, and it included a bit of business concerning a character's earrings, which were made from IUDs.

The head of the costume department, a young, “hip” female professor said she'd get those from her gynecologist.

In the rush of mounting a production, things got forgotten, and left until the last minute. So, the afternoon before Dress Rehearsal, we find the costume prof frantically phoning her doctor's office.

The nurse answering the phone said, “I'm sorry, the doctor can't come to the phone, you'll need to leave a message.”

Costumer says, “I don't need the doctor, I'm sure you can help me. I need some IUDs.”

The nurse replies, “I'm sorry, but the doctor is busy.”

Voice rising, the costume maven pushes, “I don't need to talk to the doctor. I need someone to get me some IUDs.”

There's a pause..........”SOME IUDs? How many do you think you need?”

“Well, two, of course, one for each ear.”

“I'll get the doctor. He'll explain some things to you.”
