Your Olympic tidbit du jour: 202 Nations will participate in the Parade of Nations, including Iran, Afghanistan and Iraq. As is tradition, Greece will be the first nation into the Olympic Stadium. Tradition also dictates the hosting nation is the last to enter the Stadium. This year, the Greek flag will enter first, and the Greek athletes will enter last.

anemophobia - fear of draughts
aulophobia - fear of flutes
genuphobia - fear of knees
