This is McPhail's study of a work by the artist Eric Fischl, whose work frequently deals with themes of voyeurism and sexuality.
Henderson explains of his contribution:
I was browsing through a men's magazine and came across an underwear ad with a semi-nude male wearing nothing but underwear. I thought to myself, if you want to sell men's underwear then why not put them on a woman (unless your target is a gay man). Sex sells after all.
