I don't know about you, but my day's been awesome. But maybe that's just because I'm not suffering from paraskavedekatriaphobia and I'm not living in a Norse myth. The one that's helped give 13 a bad name involves a Valhalla dinner party gone wrong...12 gods were throwing down, and when Loki--the uninvited, 13th god--showed up, he was so offended at the extent of their good time that he tricked the blind god of darkness into killing the god of joy and gladness; hence, the mayhem of thirteen. And a further note on dinners would be, of course, the Last Supper and how Judas made 13. The weekday component came one Friday the 13th in 1307, the date King Philip IV (aka Philip the Fair, not to be confused w/Philip the Handsome) had the Knights Templar arrested.
