Meta Madness
From Super-wiki
Inspired by 6.15 The French Mistake, stopitsgingertime wrote and performed the song Meta Madness. #MetaMadness was one of tags that trended on Twitter during the airing of the episode.
The song in turn tweaked the muse of Ash4897, who made a fan vid using the song and clips from the episode: The Meta Song: The French Mistake.
