We've quite enjoyed Macy's new marketing campaign in which they put together their design "stars" in fast-paced montages jam-packed with one-liners from the likes of The Donald, Martha Stewart and Jessica Simpson, who's fully come to terms with her dumb blonde schtick by agreeing to pretend she just can't figure out how to open the darn door to Macy's while schlepping boxes of her stripper shoes. But the latest spot has us confused. Featuring Mariah Carey (she has a fragrance, unlike any other celebrity we know!), Carlos Santana (highly respected shoe designer and sometimes musician!), Donald and Martha, the commercial's theme appears to be the way in which consumer goods can inspire...quasi-rhythmical snippets on Santana's legendary guitar?
