So I was in the bath, thinking about a fic I'd just read (Bittersweet by RagingSemi, a total masterpiece), when the idea hit me. Pinkie's life is fairly close to JB's in "Tenacious D in The Pick of Destiny". There's a song detailing JB leaving his family after his attempt to impress them with his art fails. I had to ponify it.
Read to the tune of "Kickapoo", by Tenacious D. http://www.youtube.com/watch?v=hvvjiE4AdUI
