Continuity mistake: When Annie is talking to Abed in the study room, next to Troy and Britta, the Dean's "Puttin' On The Ritz" cane is leaning against some books, towards the right. When the Dean comes back in to claim it, it is leaning towards the left.
Continuity mistake: You can see the play director telling a pianist with grey hair to "play something modern." About twenty seconds later when Britta throws her tea hat off towards the pianist, however, it's an entirely different piano player now, that has brown/black hair. (00:17:10)
Trivia: Actress Paget Brewster appears in this episode as an IT lady named "Debra Chambers." Brewster was eventually cast as a different character during season six named "Frankie Dart." In one season six episode, the character Dart mentions being unable to get ahold of the school's IT worker- a very subtle joke in reference to the character she played a year prior.
Question: When Troy and Abed are showing the yam to a lady she tells them that their yam was about to bloom, and that it was stepped on. I don't understand how she couldn't tell that it had been boiled? If she can tell that it was about to bloom, it doesn't make sense that she couldn't see that it had been in hot water. Of course, she wouldn't be at Greendale (I assume she is at Greendale but I could be wrong) if she was that good at something.
