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.
Alternate Character Interpretation: Link, does he really think he's Link? Or is he just elaborately role playing? (In season one, the latter is implied, as Link briefly talks about how the B Attack sucks.)
Super64 is hit on by a female player, but then Lamp hits the female player to reveal a Spambot, Super64 then asks how Lamp knew that. Cue surreal flashback and then Super64 asking what that had to do with his question, with Lamp apparently not knowing he was asked a question.
Fridge Brilliance: Why didn't Lamp's arrival help Super64 out of his prison in the Season 2 premiere? The narrator said he was a plot device, while it was stated that "not even a poorly written plot device" would save him. Which explains the random Snake cameo.
Growing the Beard: While one of the most well known series in Smash Bros. Machinima, it wasn't until Season 2 did the series finally pick up a steady stride.
I Knew It: Girem6 is Greg. Actually lampshaded too, with him stating that he thought he was "really obvious".
Misaimed Hatedom: Pimpachu is hated for being a "Poser", when he was meant as a parody of that stereotype.
