“‘The exception proves the rule’ is an expression constantly upon the lips of the ignorant, who parrot it from one another with never a thought of its absurdity.” -Ambrose Bierce
[The exception doesn't prove the rule, it disproves it. That doesn't mean that the supposed rule is not a useful heuristic, just that it is not axiomatic.]
