The 1980s - the decade in which marketing went nuts. Example one: Juicy Fruit, which was (is?) apparently the most exciting, active chewing gum ever made.
"Take a sniff / Pull it out" - was that required procedure? I don't remember a lot of people smelling their gum before "popping" it in their mouth.
There are more versions of this ad, of course - but this is the one that was stuck in my head all day today, for no particular reason whatsoever. And now it's stuck in yours. You're welcome!
