Paraskavedekatriaphobia

 A bit of trivia on this Friday the 13th. In Greece and Spain, Tuesday the 13th is considered the unlucky day. Paraskavedekatriaphobia is a fear of Friday the 13th. Finally, the 13th is more likely to happen on a Friday than any other day (with Sunday and Wednesday in a tie for second). Until April 13th, 2007, don't walk under any ladders. As always, you can visit Wikipedia for more info.
