The Widow Cobain has a wacky sense of humor:

One of the foremost experts on Kurt Cobain says the Nirvana lead singer did not pen a note mocking his wedding vows to fellow musician Courtney Love. Love herself wrote it. 

Police found the note in Cobain's wallet after he killed himself in 1994. It received a lot of media attention last week after CBS News published it, saying it was presumably written by Cobain and that it was sure to stoke questions about what role his marriage played in his death.
