Stephen King

It never crossed my mind to do this

From BookPage:

You might remember that in 2005,
a woman paid $25,100 for the privilege of having a Stephen King character—a zombie, in fact—named after her brother. (The book was Cell, and the zombie’s name was “Huizenga.”) The proceeds, earned in an auction, went to the First Amendment Project, which has also allowed bidding for characters in John Grisham, Dave Eggers and Neil Gaiman books.

Wow, $25000?
Can we get some bids on being in an index?
There's more info at the web site for more contests of this sort. Ye who feel rich, go for it!
