"Where's the beef?" became the legendary commercial catchphrase for Wendy's.

Back in 1984, the ad starred cantankerous old lady, Clara Peller, who uttered: "Where's the beef?" The commercial skyrocketed 81-year old Keller to fame - and the catchphrase is now in our pop culture lexicon. But things didn't go smooth with Keller and Wendy's - she was eventually fired from the ad campaign after appearing in a Prego's commercial that broke her contract.

Still: Where's the beef?
