A college student could not take his seminar final exam because of a funeral.

"No problem," the teacher told him. "Make it up the following week." That week came, and again he couldn't take the test due to another funeral.

"You'll have to take the test early next week," the professor insisted. "I can't keep postponing it."

"I'll take the test next week if no one dies," the undergrad replied.

By now I the instructor was suspicious. "How can you have so many people you know pass away in three weeks?"

"I don't know any of these people," the student exclaimed. "But I'm the only gravedigger in town."
