!!Characters
Dan has a tendency to [[CharacterDevelopment develop a character]] over a course of several seasons, only to [[CharacterDerailment completely throw said development out the window]] for a cheap laugh, which often isn't that funny to begin with. Many characters suffer {{Flanderization}} as the series progresses.

!!Continuity
He completely ignores it, RuleOfFunny or even just lazy writing completely over-rules any idea of continuity. If there is continuity it's almost always an episode specifically written to be in continuity (like a sequel episode).
Will completely RetCon a character to fit a single episode plot.

!!Shipping
Even though he trolls his fandom, he will use the two main types of romantic storyline in his genre, first being the JustFriends style relationship, and the other being the BelligerentSexualTension style. Admittedly this can lead to confusing shipping agendas and fan wars.
