I noticed a kind of neat little detail in "Tall Tales," and when I was screencapping it, I found an error as well.



Near the end of the episode, when we first see the scantily-clad Dean Dreamgirls, there are two blackboards in the background. At the top of the blackboard is an unusual-looking alphabet:


The letters are little people, some kissing, some holding hands, etc. A closeup, lightened a bit:
Now, what's wrong with that picture? There's no 'N'! :) What happened to the poor 'N?!'

Never fear, though, because in a different shot... The 'N' reappears:

And you can see the 'N' here, too:


Now I want to hear the story behind the alphabet itself and the missing N. :D
