Killed his own Father and married his Mother....foretold by the Odyssey. He was abandoned as an infant and didn't know who she was when they married. He stabbed his own eye out in disgust at what he had done. But I guess as long as you are just fucking someone else's mother and not your own....but even sleeping with a direct cousin can cause children to be born without fingers and or toes.

Also an 'achilles' heel...Greek comes from story of Oedepus Rex....means a weakness.

The Greeks invented the wheel.
