Struggling to find the perfect marketing hook for a new rainbow-colored string-cheese snack, Holland Mark Advertising executive Darius McLain got in touch with his own inner-child demographica purchasing sector he had all but forgotten since the onset of adolescence. 'I asked myself, what would make a kid want to buy Color Magic Cheez-bows?' said McLain, 44, after the emotional breakthrough. 'Only after looking within myself and rediscovering the 8- to 12-year-old male buried deep inside did I hit upon the ideal angle.' McLain next plans to get in touch with his feminine-urban-professional side to develop a campaign for No Nonsense pantyhose.
