Please don't call it a "Cob of Corn"!
Folks that never see it in on the stalk in the field must not know why farmers call it a ear.
Rant over.
I have lived in and around it for 34 years. I have helped plant it, take it off, and cooked it within sheer minutes of picking it. I call it corn on the cob, farmers, including my ex who is a farmer and from a farm family going back many generations call it what they want, ain't no sweat off my nose.
