If you want to be truly horrified, what till you learn that we eat bananas backwards. The monkeys do it right (of course).
I have always been puzzled by the western predilection for carving pineapples, having seen foreigns pull pineapples apart. That said, the easiest way to deal with pineapple to buy it ready sliced in a packet.
I'm always impressed by the chaps who linger by the roadside with a pile of coconuts (obvs also in the Foreigns). They deal with those coconuts using nothing other than a large machete and nonchalance. Also spouting coconuts, which frankly is the only coconut you should bother with.
