Continuity mistake: A barber is adjusting Jeff's collar when Pierce begins to talk about the country clubs he belongs to. In the next shot, there are no hands touching Jeff's collar and in the shot after that, his collar is completely covered by the barber's cape, with no barber behind him anymore. (00:20:30)

Audio problem: After Abed's fraternity runs loose, making Archie spill soda on his shoes, he expresses his dismay loudly, with commotion of the frat still being heard. Suddenly there is a very noticeable and abrupt audio cut right when Annie says her next line. (00:10:45)

Audio problem: Coach Chapman makes his way up to the white board to introduce himself and the class topic. We hear him say "Welcome to P.E.E." but his mouth doesn't open at all.
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.
