Black Handkerchief of Happiness (幸せの黒いハンカチ Shiawase no Kuroi Hankachi?) is a song that Brook sung to awaken his crew when he was alive. In a filler episode of the anime he sings it to wake up the Straw Hat crew as well. It is considered loud, fast paced, and annoying.
The CD version was released in Japan with the full song which only lasts 30 seconds. The 30 seconds involves Brook singing/shouting at the top of his lungs while playing the violin obnoxiously.

Mitsukaruna yatsu ni
|Oh White Handkerchief
Don't let him find you! 
|It's a white handkerchief|
Careful now, knees on the ground!
- The title of the song is a parody of the Japanese film "The Yellow Handkerchief" (幸福の黄色いハンカチ, Shiawase no kiiroi hankachi-The Yellow Handkerchief of Happiness).
- In addition to the soul version, "Binks's Booze & Brook Special CD" came out with a violin solo of the song.
