Toward the end of our senior year in high school, we were required to take a CPR course.
The classes used the well known mannequin victim, Resusci-Annie, to practice. Typical of most models, this Resusci-Annie was only a torso, to allow for storage in a carrying case.
The class went off in groups to practice.
As instructed, one of my classmates gently shook the doll and asked "Are you all right?" He then put his ear over the mannequin's mouth to listen for breathing.
Suddenly he turned to the instructor and exclaimed, "She said she can't feel her legs!"
