She humiliates herself

Professor Nakamura began class by using a blue dry erase marker to write an outline of today's topics on the white board.

You have a small microphone, and you're sitting in the back corner of the class. It's a large rooom, but there are only 14 students in this class, and none are near you. You quietly speak into the microhone. "Would you rather use that dry erase marker to draw a mustache on your face or draw a unibrow on your face?"

You cannot hear what she says, but you see her bring the market up to her face. She then finishes the outline and turns around to show the class she has a blue unibrow.

The class looks at each other with bemused looks.

"Would you rather tell the class you got crabs from a one night stand or would you rather tell them you got a severe anal rash from a one night stand."

"Crabs," says Dr. Nakamura. "I got crabs from a one night stand," she tells the class before briefly scratching her crotch. She walks to her desk and opens a textbook.

"Would you rather teach class from your hands and knees or teach class topless?"

"Hands and knees." Professor Nakamura puts her books and notes on the floor and gets on her hands and knees. Her case of crabs is irritating her.

You are really enjoying this, and the rest of class is just stunned.
