Incorrect Answer
When it comes to writing tests at school and university, there is a certain way that your teachers expect you to answer. Whether it be a multiple-choice test, a short or long answer test, or even an essay, teachers are looking for a certain type of answer.
And when someone responds to a question with a humorous answer, you know that no teacher is going to be happy with that. But what happens when the question is technically right but not the answer the teacher was looking for? There is no world in which this would be accepted.
