Cooperative Polygraphy - S5-E4
Trivia: This episode features a storyline involving the "Ass Crack Bandit", a student (or teacher) who is notorious on campus for dropping coins down the pants of students and faculty members. This entire storyline is a callback to the Season 2 episode "Intro to Political Science", in which the character Annie makes a brief passing reference to the "Ass Crack Bandit" during a speech.
Answer: It was part of the plot that when the boiled yam was dropped it looked like it was stepped on (which it never was). So there was no way to tell the difference between the flesh being soft because it was boiled or because it was stepped on (in the show that is, I don't know if one could tell the difference in real life). Plus, the rest of the yam wasn't boiled, so there was no evidence the yam was sitting in boiling water.
