A law first described by biologist Elizabeth Skwarecki, regarding bizarre sexual fetishes:
If you can imagine a fetish, it exists.
Corollary: and it's on the internet somewhere.
Skwarecki's law explains (or, more accurately, predicts) bizarre fetishes like being turned on by: statues, amputees, people who are very tall or very short, eating feces, murder, being treated like a baby, enemas, smoking, sporks, scars, balloons (yes, balloons), and being suspended (not to be confused with hanging). Many more are catalogued under the fetish node.
