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.
During the last few minutes, she was seen desperately throwing the coin, mumbling and sweating.
The moderator, alarmed, approached her and asked what was going on.
"I finished the exam in half an hour. But, I am rechecking my answers."
