Based on an early 19th century flag used by Greeks fighting for independence from the Ottoman Empire. The motto reads Dolmades E Kleftiko! or Stuffed Vine Leaves And Lamb Marinaded In Spicy Sauce! This is believed to hearken back to the first meeting of rebels being in a rather nice taverna with a good menu, and after a surfeit of retsina, the revolutionary manifesto being hastily scribbled down on the back of the menu. The Prostitute tasked with running up the revolutionary flag unfortunately got the motto slightly wrong.
