Dan discovers a monster under his bed, and, of course, nobody believes him.

----
!!This episode contains examples of the following Tropes:
* AngryFistShake: First at the fake monster under the bed, then at Chris when he learns... it was all a trick!
* ArbitrarySkepticism: Despite the fact that Chris and Elise have witnessed supernatural stuff like werewolves and alien spacecraft, they both have a hard time believing in Dan's story. Justified as A) it's [[PsychopathicManchild Dan]] and B) it was all part of a plot they conceived so that they could get rid of Dan for a week.
* BatmanGambit: Chris pulls a rather elaborate one so he and Elise can go on vacation without being pestered by Dan.
* BewareTheNiceOnes: Who would guess NiceGuy Chris was the one behind all this?
* CassandraTruth: Subverted. Dan is actually right about something being under his bed, but neither Chris nor Elise believe him at first... except he was actually wrong, and the whole thing was a hoax by Chris and Elise.
* ContinuityNod:
** When Dan drives to Canada, he sees that the country still hasn't recovered from the avalanche he caused in [[Recap/DanVsS1E6DanVsCanada "Dan Vs.Canada"]].
** Madame Zelda from [[Recap/DanVsS1E12DanVsGeorgeWashington "Dan Vs. George Washington"]] makes her return in this episode.
** Dan and Chris eat at the bakery Ninja Dave opened at the end of "Dan Vs. The Ninja".
* CosmicHorrorStory: At first it appears that Dan is being pursued by a [[Literature/CthulhuMythos Cthulhu]] lookalike, but it turns out to be a Subversion.
* MyGodWhatHaveIDone: Subverted. Dan observes how Canada never recovered from the avalanche and seems genuinely remorseful, but then he offers a glib "Oh well" and carries on like nothing happened.
* OhCrap: Dan after he starts reading the letter and realizes what was really going on.
* ScoobyDooHoax: There's no monster at all. It was all just a ploy devised by Chris with Elise's help.
* ShoutOut: The supposed chant that Dan attempts includes the phrase "[[WesternAnimation/{{Cinderella}} Bibbidi-Bobbidi-Boo]]."
* ThingsThatGoBumpInTheNight: Dan is being terrorized by one. However, as already described above, it's a Subversion.
* TheWorseningCurseMark: A shrewd trick by Chris.
* UnusuallyUninterestingSight: Dan falls into Elise's Dan Trap (large mousetraps by the bedroom window), to which Chris offers a mild "What's new?"
