I was at a grocery store recently when I heard an expression that often makes me laugh. A man held up a bunch of grapes, each of which was as large as a golf ball, and said to his wife, “These aren’t your grandfather’s grapes.” I think he was referring to how GMO technology is filling our markets with fruit-on-steroids, the politics of which is a conversation for a different time and place (Friday Night Open Thread, anyone?). It was the expression that caught my attention more than the actual grapes. I’m not sure why, but “This ain’t your grandfather’s whatever” usually strikes me as a funny way to comment on the evolution of a particular thing.
