Widow throws party to find place in heaven

And certainly not the only one to have done it. One person leaps to mind immediately:

"Wrote her will shortly before her death. Drawing up the document with her Los Angeles lawyer, she set aside $2500 for her friends to throw a party in the event of her death. After she died of a heroin overdose on October 4, 1970, her friends followed her wishes and threw a party in her honor at a club in San Anselmo, California. The party invitations read: "Drinks Are On Pearl."" - from IMDB.com
