The Cheating Exam
A college student is sitting for his final exam. Halfway through, he realizes he doesn’t know the answers.
Desperate, he writes on the exam paper: “Dear Professor, I don’t know the answers, but here’s $20. Please give me a passing grade.”
The professor grades the exam and returns it the next day. The student sees an F on his paper with a note attached:
“Here’s your $20. I don’t take bribes, but I do give refunds!”
