1984 had a lot to offer.
The Apple Macintosh went on sale for the first time, Michael
Jackson caught on fire while filming a Pepsi commercial, the
Space Shuttle Discovery took off on its maiden journey, and
Clara Peller first asked the question, "Where's the beef?"
Wendy's used this as their ad
campaign from 1984 until 1985. The phrase caught on faster
than you can say "wake me up before you go go" and is still a
part of our slang today (although perhaps a little less used now
than then). See Clara do her thing in the video below.
