The joke has been explained to me. The cartoon shows four
characters from "The Wizard of Oz", and the viewer is supposed to
ask, "Which one of these is not like the others?" We see that the
Scarecrow is enjoying licking his two-scoop ice-cream cone, while
the other three are holding a hand to their forehead as if they have
a headache. But the biggest clue (which I missed entirely) is found
by hovering the cursor over the cartoon, which produces a label
[Brain-Freeze]. This is otherwise known as as
https://en.wikipedia.org/wiki/Cold-stimulus_headache
"A
cold-stimulus headache, also known as
brain
freeze,
ice-cream headache,
trigeminal
headache[1][2] or its given
scientific name
sphenopalatine ganglioneuralgia (meaning
"pain of the
sphenopalatine ganglion"), is a form
of brief pain or
headache commonly associated with
consumption (particularly quick consumption) of cold
beverages or foods such as
ice cream and
ice pops. It is caused by having something cold touch
the
roof of the mouth, and is believed to
result from a nerve response causing rapid constriction and swelling
of blood vessels
[3] or a "
referring" of pain from the roof of the
mouth to the head.
[4][5] The rate of intake
for cold foods has been studied as a contributing factor.
[6][7] A cold-stimulus
headache is distinct from
dentin hypersensitivity,
a type of pain that can occur under similar circumstances.
Cats and other animals have
been observed experiencing a similar reaction when presented with a
similar stimulus.
[8]"
That last sentence explains the Japanese expression "nekojita" 猫舌
(cat-tongue), which is glossed as "a dislike of very hot [or very
cold!] food or drink".
Another reason I did not get the joke is that I have never
experienced an ice-cream headache, possibly because of my high
intracranial cellulose content.
The title of the cartoon, "One Advantage of Being a _____", is
generic, and is a clever way of saying "______s are brainless." I
am glad someone told me the joke, because otherwise I would waste a
lot of time contemplating every little feature of the art work, such
as: Why does the lion have only four toes? Why is the Tin Man
wearing Turkish slippers? Why is Dorothy's hair in a braid (it
wasn't in "The Wizard of Oz")? Why does the Scarecrow have such a
grotesquely enormous tongue? Why are the Scarecrow's pupils of
unequal size?
