History Recap / BoyMeetsWorldS5E17AndThenThereWasShawn

* GettingCrapPastTheRadar: Several in the Creator/DisneyChannel version of this episode:
** At the beginning, the word "hell" is cut out when Mr. Feeny chews out the gang for disrupting the class:
--->'''Mr. Feeny:''' Now listen! This class will not be interested in the romantic goings-on of its students than it is with whatever the hell I am teaching!
** When the gang suspects Janitor Freddie is the killer after Kenny and Mr. Feeny are killed. As the gang hears his squeaky dustbin approach the classroom, "Oh, my God!" is cut out when Angela starts to freak out, to which the gang eventually finds Freddie's dead body in the dustbin.
--->''[the gang hears the squeaking of Janitor Freddie's dustbin get louder]''\\
'''Angela:''' Oh, my God! He's coming closer! He's coming! He's coming for all of us!\\
'''Jack:''' Come on, let's get out of here!\\
''[the gang bolts from the classroom, but Freddie is nowhere in sight, just his dustbin without someone to push it]''

* WhooshInFrontOfTheCamera: The killer does this twice: the first time when they try to find a way out, but no luck (at which point Feeny pops up, only for the gang to find he was killed) and the second time after the gang finds the janitor's body.

(''this is quickly cut off, as the killer dumps more books on Feffy and Eric, killing them both'')

* TenLittleMurderVictims: There is a killer lurking around in the school, but with Mr. Feeny and the Janitor Freddie ruled out as suspects, could it be someone else or one of the students?

** Averted by the actor who plays the janitor (who has no lines, and is therefore uncredited). It was long-rumored that he had been played by [[https://www.imdb.com/name/nm0877185/ Joe Turkel]], who had played Lloyd the Bartender in ''Film/TheShining'', but the producers confirmed that this was not the case. It was just somebody with the right "look".

* EvilDoppelganger: [[spoiler:When Cory, Topanga and Shawn confront and unmask the skull-faced killer after he kills Angela and Jack, he is revealed to be an evil double of Shawn.]]

* SpecialGuest: Richard Lee Jackson as Kenny (the first victim of the episode who has a pencil impaled in his head), and Jennifer Love Hewitt as Jennifer Love "Feffy" Fefferman (the penultimate victim who is killed by having library books dumped on her along with Eric).

* DreamEpisode / AllJustADream / OrWasItADream: The whole episode turns out to be a nightmare Shawn was having and near the end, after he awakens from it, it leads him to believe it's his fault Cory and Topanga broke up. Mr. Feeny lets the gang leave, considering they were all punished enough, but moments after everyone leaves the classroom, the skullfaced killer comes out of hiding, and exits the darkened classroom, as well, ending the episode. This is also followed by a cold ending, where Feeny dreams that his classroom is more well-behaved in a military fashion, only for him to awaken to a rowdy class and considering going on a killing spree himself.

* LetsSplitUpGang: When the gang tries to hide from the killer in the library:

'''Cory:''' Well, Kenny, it's certainly not going to be any of us!

* ThrowTheBookAtThem: Eric and Feffy are the penultimate victims of the episode and this is how they are killed while the gang is hiding from the killer in the library. The killer dumps dozens of library books from their shelves, crushing them both to death.
