These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Big Lipped Alligator Moment: Luffy and Zoro's battle of the beards at the end of Episode 4. Not that it's particularly unusual by this series' standards, but most of the show's other weirdness is at least somewhat relevant to the plot.
Tropes Are Not Bad: Thing is, a lot of people think that the second version of episode five is boring and unfunny, with the exception of a small couple of lines ("Your mother gave birth to a fart", most notably).
The non-fanfic episode is almost certainly just an exercise in Stylistic Suck in reaction to all the nagging. He did produce it in a fraction of the time it normally takes him and it's half bloopers.
