I came up with this in math class

This guy goes to interview for a job. He’s really nervous about it, because this job is a super big opportunity for him. He goes in, and the interviewer introduces herself, saying “Hi, my name is Karen”. They immediately start talking about the job, and the guy is answering all of Karen’s questions spot-on, and he’s starting to feel really good about his chances of getting the job. But surprisingly, at the end of the interview Karen says “Thanks, but I think we’re gonna move on with other candidates.” So the guy leaves, feeling pretty sad and disappointed. On his way back to his car, he passes an old woman in the parking lot. She waves him over, and says, “Excuse me, young man”. The guy walks over to her, and she says “Hello, dear. My name is Sharon”. “Could you do me a favor? I left my purse at home and I don’t have any quarters for the parking meter.” “Oh no problem,” he says, and grabs some change from his pocket and hands it to her. Suddenly, Sharon reaches up and starts pulling on her face, and her face starts peeling off! She’s wearing a mask! And you would never believe who it was under the mask: it was Karen, the woman who just interviewed him! Karen explains that it was all a test, that she needed to make sure he had good character before she would hire him. “Congratulations,” she says. “You got the job!” So he signs on for the job, goes home, still shocked and a little confused. Anyways, it all just goes to show that Sharon is Karen.
