Other mistake: In "Broadway Bro Down," when Shelly and Larry are playing Settlers of Catan, Shelly tells him, "And I got a victory point for the most roads connecting settlements." In the game, there's a two victory point bonus for the longest road, but no points for getting the most roads.
Plot hole: Mr Mackay says he has been working hard on the tooth decay play for 6 years. When he says why it's so important to him, he says it is because it took his father 2 years ago. The monologue exaggerates the length of time he's spent working on the play by saying it was a long time, and exaggerates how hurt he still is that his father was lost by saying it was quite recent. Perhaps the two numbers were stated the wrong way around.
