An interesting error in an essay called "Blade Runner Brilliance," with the amusing subtitle of "As 60 leading scientists attest, the movie is more relevant and important today than ever":

"To complicate things, the differences between humans and replicants are so minute that a sophisticated procedure called the Voight-Kampf [sic] test is required to flesh out the latter."

Presumably the author meant flush out, but all the talk about humans and replicants put the word "flesh" in his mind instead. Despite my recent near-religious commitment to reading Language Log I can't decide whether this is an eggcorn or a simple malapropism that happened to be motivated by the topic under discussion. By indicating that it may be a common confusion, I think this page contributes to the eggcorn argument.
