March 14 is National Potato Chip Day.

The popular snack was invented by accident by chef George Crum in 1853 in Saratoga Springs, New York. He was trying to get back at a customer who had complained that his French fries were too thick. Too thick? Fine, eat this! And since petulance always produces the best snack foods, potato chips were born.

Ah, but the chips were all different shapes and sizes and could not be easily stacked. This could not be borne, so in 1968, Proctor and Gamble introduced “Pringle’s Newfangled Potato Chips,” which were uniform in size and shape and came in a convenient canister. But other potato chip manufacturers complained (rightly) that Pringle’s were not true potato chips, since Pringle’s were molded from processed dehydrated potato particles. That is why Pringles no longer brands itself as a potato chip. (And curiously, it also lost its apostrophe.)

So then why even talk about Pringles on National Potato Chip Day? Because it gives me an excuse to post one of my favorite jingles, the original 1968 jingle for Pringle’s Newfangled Potato Chips. Watch it and sing along!
