A company is interviewing applicants for an accountancy position, and the three finalists have been chosen.

The first one is called in, and asked, "What is two plus two?"
She answers, "Four," and is asked to leave.

The second finalist is called in, and asked the same question, "What is two plus two?"
He also answers, "Four," and is also asked to leave.

The third and final applicant is called in, and yet again asked, "What is two plus two?"
He answers, "What do you want it to be?"
