"Where's the Beef?"
That one line in a commercial back in 1984 made 82-year-old Clara Peller an instant television icon. David Albert, who teaches advertising at Arizona State University, says the woman was unique.
"Peller was an unusual looking lady who spoke unusually and quite frankly, and she was differentiating herself from everyone else in the marketplace at that time, and that made her worth watching," Albert said.
Appealing to our elite tastes, advertisers also found a way to put mustard on the map.
"Pardon me? Would you have any Grey Poupon?"
They also taught us all how to spell bologna, because now we know Oscar Mayer has a way with B-O-L-O-G-N-A.
But Albert says memorable doesn't guaranteed gold. Take Taco Bell for instance and their "Yo quiero Taco Bell" campaign.
"Everybody knew the dog by heart, but they lost money and the president lost his job," Albert said.
So, it appears there's really no formula for the perfect ad.
"No, no," Albert said. "If there was, then everybody would be advertising successfully, and they're not."
Jingles like Alka Seltzer's "Plop Plop Fizz Fizz" are practically timeless, just like Slinky's and kids.
"Everyone knows it's Slinky."
Now, just try getting them unstuck from your mind. And here's one more that will keep you humming all day long:
"I am stuck on Band-Aid brand because Band-Aid's stuck on me."
