Some friends from IRC and I were playing Graffiti on Yahoo Games just now (it's Yahoo's online version of Pictionary). One of the words keeper1st was trying to get us to guess was "CD". He drew this... round thing... with some music notes next to it... guesses were flying left and right, all of them wrong... in desperation I quickly typed "music donut". The game marked it as correct!
Because, see, the words "music donut" contain the string "CD". So... music donut it is!
