The 62-year-old Black Sabbath frontman said that he is trying to organize jokes and pranks for when the time comes to keep everyone laughing.
Writing in his health column for The Sunday Times Magazine, he explained, 'I don't care what they play at my funeral; they can put on a medley of Justin Bieber, Susan Boyle and We Are The Diddymen if it makes 'em happy - but I do want to make sure it's a celebration, not a mope-fest.
'I'd also like some pranks: maybe the sound of knocking inside the coffin, or a video of me asking my doctor for a second opinion on his diagnosis of 'death'.
'There'll be no harping on the bad times. I don't want my funeral to be sad. I want it to be a time to say 'thanks'.'
