Awesome Music: One can't deny that the person has excellent taste in classic video game music.
Big-Lipped Alligator Moment: All of his videos can be summed up with this trope, but one notable example is in Dude Time. After RED Soldier sprays himself with Dude Time, he is approached by Scout's mom, who has Blank White Eyes. RED Soldier then has a seizure and four BLU Soldiers pop out of him, form a line, and explode. That in itself fills the "appears out of nowhere" and "strange in context" criteria, but then it takes "never mentioned again" to the extreme because, once the BLU Soldiers explode, the earlier clip of RED Soldier spraying himself with Dude Time is played again and, this time, he walks away with no reference to the earlier scene with Scout's mom and the BLU Soldiers, as if implying that what just happened never happened.
From "Sniper's Video Game Adventure", for a second, Sniper looks to his right to find a giant Orca. The orca then says "Fire bomb!" and explodes.
Colbert Bump: Just about any music they use in their videos and references in their comments end up being raided by comments referencing the videos the music that have been used in on YouTube. It is inevitable, and RubberFruit themself absolutely hates it.
Special Effects Failure: Deliberately done. Raiden and Sam's "final fight" is represented by them... swinging their swords in weird and unwieldly ways via SFM. Raiden swings his blade up and down and Sam just moves his this way and that. Oh and Sam's face.
