Somewhere along the evolutionary path from proto-simian through hominid, something got lost. A skill possibly instinctive, but most likely cultural. Taught from generation to generation, "Monkey See, Monkey Do".
Now, though it's taken awhile, a network of interlinked computers spanning the planet is propagating this rediscovered knowledge.
How to peel a banana, properly.
Human see, Human do. It is our way to propagate knowledge through prosthetic memory though, be it cuneiform tablet or Internet video. It's our style, what we as a species, do.
Yes, I've tried it. The only bit that gets squished is the fibrous black bit on the end that no-one eats anyway, and the stalk provides a convenient handle. Be warned though, the end bit isn't anchored firmly to the skin, so the whole banana slips out rather easily if you're not careful and peel too far.
