I’ve long dissented from the claim that it’s hard to compare apples and oranges:
We compare apples and oranges all the time! We compare them by price, by how much we like the taste, by likely sweetness and ripeness, by how well they’ll go in a tasty fruit cocktail, and so on. In fact, every time we go to the store and buy apples rather than oranges — or vice versa — we are necessarily (if implicitly) comparing apples and oranges.
I hereby move that the phrase be changed to reflect two items that really are radically dissimilar — say, “comparing apples and democracy,” or “comparing oranges and the multiplication table.” All in favor, say “aye”; all opposed, say “nay”; motion carried. It’s Now Official; use them in good health.
