Currently, SMG4: Stupid Luigi's Mansion and R64: Stupid Smash Bros are the only videos in the series to neither have Mario in their name nor to be parodying games that are about Mario.
As of April 2020, R64: Stupid Mario Maker is the highest viewed video in the series, with over 10 million views.
Even though Retarded64 is no longer used in the title of SMG4's videos due to the series being canceled, SMG4: Stupid Mario Sunshine still contained its intro, hinting that it would have been included in said series.
For some reason, a video for the song Dearly Beloved from Kingdom Hearts 2 was included in the playlist. It was later removed.
