Christmas 2013: The 12 Idiots of Christmas, more often simply called The 12 Idiots of Christmas, is the 157th video made by SuperMarioGlitchy4, and his third Christmas Special blooper. It's a song-style Super Mario 64 Blooper specially released by for Christmas 2013, which parodies the song The Twelve Days of Christmas, and includes SuperMarioGlitchy4's usual humor, running gags, and gay jokes as well.
Waluigi's line "eleven shirtless men" references a scene from R64: Idiot karts 101 where Waluigi takes off his shirt. This scene also appears in this blooper.
When Peach sings her line for the first time, she also says that the princess threw something at her, despite Peach being the only one usually to be called "the princess". It may be Daisy who threw the magic rocks at her, but this is unlikely due to her few appearances.
When Weegee says 'Weegee weegee weegee' an image of possibly brentalfloss appears.
