There was once a medical student specializing in pathology who truly wanted to excel in his studies. Without fail, he would daily visit the school’s path lab following his classes to do extra work. One evening he uncovered a cadaver only to notice a cork plugging its rectum. Curious, he removed the cork only to hear, "On the road again, I just can’t wait to get on the road again..."

Startled, he replaced the cork. Curiosity soon got the best of him and he, once again, removed the cork. Again, he heard the same tune, "On the road again, I just can’t wait to get on the road again..."

He could stand it no more. He replaced the cork, covered the cadaver and raced upstairs to his professor’s office. He persuaded the man to accompany him back to the lab. Once there, the student again uncovered the cadaver and displayed the corked rectum.

The professor looked unfazed. When the student removed the cork, the same tune emanated, "On the road again, I just..."

The professor looked bored and started to walk away.

The student was aghast at this casual response. He said to the professor, "Don’t you find this amazing?"
