Back then, a womans bare ankle was hard-core pornography.
In olden days a glimpse of stocking
Was looked on as something shocking...
--"Anything Goes"If a show has an episode set in the 1800s or early 1900s, or is referring to that era, expect mention to be made of The Ankle Taboo. This is often played for laughs; a picture of a bare ankle will be referred to as pornography, and the sight of one will induce much shock, scandal and monocle-popping. Other times, "can't show your ankles" will simply be used as short-hand to sum up all of the repressiveness of that era. Note that a *lot* of things we tolerate today were severely frowned upon in those days (and vice versa), but the exposed ankle is probably one of the easiest, quickest, and (in today's culture) silliest examples of Values Dissonance that a show can portray, and thus works best for a quick gag. A subtrope of Fully-Clothed Nudity and Our Nudity Is Different. See Also: Foot Focus, or Changed My Jumper for when this comes into play with time travelers.
