The line comes from the NBC sitcom 30 Rock, where Steve Buscemi plays a private investigator who goes undercover at a high school in a backwards cap and a Music Band T-shirt, carrying a skateboard.

It remains popular because the setup needs no explanation, brands, parents, politicians and older gamers all fit the same template instantly.
