Quote:
“I thought it was just a can of corn, a popup. I started to round first base and I saw him kind of staggering a little bit, and I thought, ‘wait a minute, he wasn't wearing any sunglasses.’ That sun out there is brutal. Sure enough, it dropped in front of him.”
This term is much older than you might think—it dates from the late nineteenth century. And while there are several theories about the origins of this term, the most charming comes from the grocery store.
Shops used to keep canned goods stacked high and sales clerks would knock the cans down with a wooden pole before catching them easily with an open hand or apron.
But that isn’t the expression’s only meaning. When Robin Williams won an Oscar for his portrayal of a psychiatrist in the movie Good Will Hunting, he told South Boston residents “You're a can of corn. You're the best.” In Southie (South Boston) that’s slang for good-natured and easygoing.
