Triskaidekaphobia

Rico says, since there is one this year:

The connection between the Friday the 13th superstition and the Knights Templar was popularized in Dan Brown's novel, The Da Vinci Code. However, experts agree that this is a relatively recent correlation, and most likely a modern-day invention. Although, according to many Freemasons, this date corresponds with the slaughtering of the Knights Templar by the Catholic Church: "On Friday, 13 October 1307 (a date sometimes linked with the origin of the Friday the 13th superstition) King Philip IV of France ordered de Molay and scores of other French Templars to be simultaneously arrested."

Sounds like a reasonable association to Rico...
