My dad had a class in medical school where the professor dipped his finger in a beaker, talked about mechanisms for sugar in diabetic patients’ urine, and then proceeded to stick his finger in his mouth. He had all of the students do the same, who noted that the sugar was apparent.

He concluded the class by talking about the importance of observing patients, and pointed out that he had tasted a different finger than the one he had put in the beaker.
