"That idea of 'not cutting corners' is not far from the actual truth," said Frank Vamos, director of brand communications for the company.
Dave Thomas' Grandma Minnie instilled that oft-repeated phrase into her grandson. When he founded Wendy's -- he kept that in mind.
"That's a message Dave Thomas wanted to instill throughout the company so it's definitely symbolic," Vamos said.
"Another big reason is that Dave was always very confident in the quality of our meat. He wanted to make sure that the patty sticks out of the bun so that everyone can see it, see the juiciness. And the square patty does that," he added.
Over the course of time, the square patty has become just as iconic as the logo, or the Frosty. And that old dad joke actually explained it all.
