U.N. Owen Was Her?!
A song originally from the weeaboo-ish PC game Touhou 6: Embodiment of Scarlet Devil. It is the theme song to the extra stage boss, Flandre Scarlet and whatnot.
It has been made into a lot of remixes for the Youtube Poop Music Videos. There's one involving Mama Luigi, one involving Uctions, one involving Dr. Rockso, The Rock & Roll Clown's cocaine, and even one involving Dr. Robotnik's penis. However, the most famous one out of them all is the one involving a Japanese Ronald McDonald saying and doing random shit while being synched to this song. Recently, this song has been overshadowed by others such as "Gentle Breeze" from Trauma Center: Under the Knife 2, "Sand Ocean" from Kirby's Dream Land 3, and other songs like that.
