Costume Shop Ad Says Halloween Is the Only Time of Year to Dress Up

As I was driving to my friend's apartment today for our work-out date, an ad interrupted my music to bring me nothing but bilge.  And by bilge, I don't mean that the content wasn't worth the listen; in fact, I was glad to hear it was for a local costume shop discussing what it could offer shoppers for Halloween.  So what was bilge-y about the ad?

Because it started out by claiming Halloween was the only time of year you could dress up to be someone else.

Um... excuse me?  Where do I even begin?
