In this joke ad for Head & Shoulders dandruff shampoo, a
group of Millennials is hanging out, and when one member of the group throws
shade on another one, the object of the barb makes the gesture of brushing
something off of his shoulders. Then we freeze frame on the guy making the
brushing off his shoulders gesture, and the announcer chimes in, saying: “That
brushing something off your shoulders gesture could mean you have dandruff! Use
Head & Shoulders dandruff shampoo to get rid of dandruff and that brush it
off gesture for good!” Then, as a tag, we see the same guy who initially
insulted the shoulders brushing guy walking with a group of friends, and as
they walk past the shoulders brushing guy, he says: “Hey, have you solved your
dandruff problem yet?” And the whole group laughs at him.
(BTW:
This is a joke on the old Head & Shoulders ads from the 1970s and ‘80s
where someone would scratch their head, and the announcer would say: “That
little itch could mean you have dandruff!” And that made everyone
self-conscious about scratching their head for the next 20 years.)
