If you are wondering what a Goober is, there is a picture of one at:

The Goober reported for her University final examination, which consisted of "yes/no" type questions.
She took her seat in the examination hall, stared at the question paper for five minutes, and then in a fit of inspiration took her purse out, removed a coin and started tossing the coin and marking the answer sheet - Yes for Heads and No for Tails. Within a half an hour, she was all done whereas the rest of the class was still sweating it out.
