@VINT64 Basically:
-Husband asked the wife to get the car inspected because the pamphlet said that women have discounts
-Beauty pack course = she needs to choose this course for that discount
-She thought that the husband was talking about pack (verb) and not pack (noun) which led her to say she's not interested to pack (something or someone)
-Husband corrected her by saying he was talking about the other pack.
-"Just what-- Just who did you think you'd pack?" (what = car, who = husband)
I'm honestly not sure, but this is what I think.
