I grew up In South Africa and remember a peculiar twist on an old aphorism.
Many hands make lice work.
I arrived at this mutated quotation for two reasons. The not unusual experience of observing a troop of monkeys engaged in communal grooming and a belief that aphorisms should be something more than mere recitations of obvious truths. I've come to realize aphorisms reflect the obvious because it is seldom apparent to many of us. The original version of this old saw, while it lacks the ingenuity of my twisted creation, is never the less more useful to those of us who pay attention to the obvious. Many hands do make light work.
