Sturgeons law

Sturgeon's Law: "Ninety percent of everything is crap." Derived from a quote by science fiction author Theodore Sturgeon, who once said, "Sure, 90% of science fiction is crud. That's because 90% of everything is crud." Oddly, when Sturgeon's Law is cited, the final word is almost invariably changed to "crap".
