The shrill, strange, contagious sound that Brook from the anime "One Piece" makes when he laughs.
Brook (English Translation): "It has been over a few decades since I have eaten anything decent. It became so painful that the back of my stomach and my back were almost indistinguishable. That was the kind of life I lived for so many years. Then again, I am a skeleton so I don't have a stomach or back. Yohohohohohohohoho... SKULL JOKE!"
