Fun Facts regarding "I Can Take Off My Panties!":

* The entire thing was written in one sitting.

* This file is a lot of fun (the hands on Expert exemplify this).

* Yes, you read the song's title correctly.  If you're wondering what the
  lyrics are about and can't be bothered to watch the video:
  * Verse 1: She basically states her belief that she thinks taking off her
    panties is what will make her an adult.  (So chorus 1 is "pantsu nugeru
    mon," which means "take off my panties.")
  * Verse 2: She ponders if she should, citing that she doesn't think she's
    ready for the responsibilities of adulthood; contrasting with the first
    verse, she figures she can put her panties back on to be a child again.
    (Thus, chorus 2 is "pantsu hakeru mon," meaning "put on my panties.")
  * Verse 3: She comes to the conclusion that she's at an in-between age
    where she really isn't either an adult or a child, and should make her
    decision when she's ready.

* As of the December 2011 pack iteration, the Expert chart has been
  uprated to an 11.
