The Beatles legend is keen for his friends and family to celebrate his life rather than mourn him when he dies.
McCartney said: "At my funeral, I want jokes to be told and old funny stories rolled out."
"I want my family and friends to have a laugh. I want them to celebrate my life rather get depressed about my death."
The 65-year-old musician also revealed he finds playing the guitar therapeutic.
The "Hey Jude" singer - who is currently embroiled in a bitter divorce with Heather Mills - says he is able to forget his troubles whenever he picks up the instrument.
He said: "I play the guitar for my own enjoyment. It's therapy, anyone who plays the guitar knows that. You just sit there playing and you're taken to another world."
