Retaking exam
Four college students missed an important exam, choosing to party instead. They go together to their professor the next day, and said, "We're sorry we missed the exam. We had a flat tire on the way to class. Is there any way we could possibly take a re-test?"
"Sure," replied the professor. "Come on in tomorrow, and you can all take a retest. But remember, it's a pass or fail."
The four students arrived the next day to take the retest, and all of them sat down in their seats. Before handing them their exams, their professor told them, "I've got good news and bad news. The good part is, there's only one question on the test. The bad news is, if any of you fail, you all fail the test."
The students sat there, a bit worried from this professor's strange introduction to the exam. Then the professor handed out the four exams, and each student stared down at their papers, which contained just one simple question:
"Which tire was it?"
