"Someone called all the newspapers in New York and told them I'd died. I've been told by almost everyone it was an ex-wife - I've had a few so it's hard to pinpoint which one - but who knows for sure?"

In this quote, Richard Pryor is reviewing a strange and upsetting experience he had where someone falsely reported his death to all the papers in New York. He reveals that lots of people have hypothesized that it was among his ex-wives who made the call, but he is uncertain and can not identify which one it might have been. This highlights the complicated and troubled nature of his past relationships and the truth that he has had several marriages. The use of the expression "who knows for sure?" recommends that Pryor may never ever truly understand the intention behind this strange incident, including a sense of mystery to the circumstance.
