Emily wants her husband, John Cullum, to explain why he goes to commercial auditions, but never gets chosen.
Is it his Southern Accent?
JC demonstrates. In a Southern Accent he pretends to sell a Ford car; then, sells the Ford ala John Gielgud; then, tries again, selling the car in a Richard Burton style and tone.
They discuss the fact that some advertisers have asked him to present their product in the style and tone of "Holling the Bartender" -- the role John Cullum played in the TV Series, "Northern Exposure."
Emily suggests that JC doesn't get ever get the job because he really doesn't want to do commercials..
