As your teacher, I find your latest Human Anatomy test really disappointing. Do you really want to become a doctor with these grades? I'm very angry with you, I feel like I'm wasting my time teaching you how the human body works! I question you, and you can't answer anything. Then all of a sudden, when I'm almost convinced to let it all go.. I remember one thing. Well, of course I can't explain to you what I'm going to do, you just have to know that it's the best way to learn human anatomy through direct observation! Close your eyes and... ...you suddenly find yourself on the ground, while with your nose upwards you see me approaching, as tall as a skyscraper. I grab you and swallow you in my giant mouth. Your journey begins! I can hear you getting into my stomach and then into my colon. You can clearly see my intestine from the inside (endoscopy) while the sound of my heart fills your ears. The cramps I feel are atrocious, but I want you to become a good doctor one day! Finally, the end of your journey has come. I sit on the toilet and start to push until something enters the water with a "splash".. it's you! Now you will surely be able to respond correctly to the next test.
