The recent DirecTV commercial with the image of the late Chris Farley cavorting with David Spade begs the question – which living celebs have that kind of afterlife? Will Jay-Z's relatives have 'Hova sell a Honda? Will Taylor Swift's estate have her pushing a Swiffer when she's pushing up daisies? What about today's reality TV stars? Any post shelf-life prospects?

"No," says Amy Ferguson Wolf, director of film & TV at mediaplacement entertainment, a branding company which strategically inserts products into what you're watching. "It's fast food fame – digested and quickly forgotten. Being famous for something other than 'being famous' is essential." So who is a candidate for post-mortem stardom?
