That's how it works with
all the Got Milk ads -- from those featuring Austin Powers,
to those with Hillary Duff, Nelly, Jason Kidd. What is making
you buy milk isn't they authority of the celebrity as a spokesperson
for milk, but rather their cultural status -- and the fact that
they are willing to look ridiculous to sell a dairy product.
To a certain degree, the ads themselves have become part of
the argument: people are waiting to see who is hip or hot or
cool enough to be in the latest Got Milk ad.
Advertisements make these
sort of arguments all the time. Think of the ads that use celebrity
spokespeople. From Nike (i.e. Michael Jordan) to KFC (Jason
Alexander) to Pepsi (Britney Spears), companies trade on celebrity
status to sell products. That is, their ads make arguments centered
specifically around celebrity appeal.
