This is for the gamers that actually finished Portal from The Orange Box and got to hear the wicked end song, "Still Alive" created by Jonathan Coulton, and sung by the defeated end boss, GlaDOS. I wasn't one of those people, but I still heard the song and that's what counts. Right?
Anyway, Rob Balder has created a cute parody of the Portal end song, which features another famous end boss. The song, "Still Annoyed" features Bowser of Super Mario Bros. fame singing his own version of an appropriate end song. Rob felt that GlaDOS shouldn't be the only end boss to get his own song, so he made one up for Bowser.
Click the play button in the box after the jump to hear this cute parody.
Thanks Reaper for the tip!
