Character mistake: Annie when giving her gifts is holding two little mini flags to cover the possible ethnicity of Shirley's baby. One is a Chinese flag and the other is Zimbabwe. Annie makes reference to the fact that the ethnic food she made is one from Ghana. She makes Ghana ethnic food but does not get the right flag for Ghana. She decorates the table with numerous flags which are also Zimbabwe.Lummie
Revealing mistake: When Chang's paint bomb explodes, pay attention to the background. You will see paint exploding from three different points on the ground. (One to the center, one to the left and one to the right) The only problem is that there was only one paint bomb in the center, so it makes no sense that there are 3 explosions from different points.
Trivia: This episode features a pay-off for a joke that was established in the first two seasons. In season one, the character Professor Slater mentions the name "Beetlejuice" while trying to recall Britta's name. In season two, Britta refers to Jeff's underwear as "stripey Beetlejuice numbers" during a conversation. And in this episode, Annie says that Britta has the "Beetlejuice" soundtrack on her computer. As Annie says the name, the character Beetlejuice is visible briefly walking by a window in the background, his name having been said three times. (In the film "Beetlejuice", he is summoned once his name is spoken three times).
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.
Trivia: The character Annie Edison was originally written to be either Asian or Latino, but Alison Brie did so well in her audition that she was cast. The character of "Annie Kim" (sometimes referred to as "Asian Annie") is essentially an inside joke, as she is an Annie-Edison-like character portrayed by an Asian actress as Annie was originally conceived, and serves as a "rival" to Edison throughout seasons 3-6.
Question: Something I don't get... If Willy the prisoner is not really a killer, as revealed in the climax, then why did he try to literally kill Jeff earlier? It goes against the whole joke of the episode - that Willy is actually a fairly harmless fraud who never actually killed anyone despite his claims. He was just sort-of a loser who built a mystique around the fact he was (wrongfully) convicted of murder. The fact that he did try to kill Jeff therefore just doesn't quite add up in my head.
