Snakes on a Plane and short film parody competitions. On July 6, 2006, the official "Snakes on a Plane" website started a promotional sweepstakes called "The #1 Fan King Cobra Sweepstakes". The contest made innovative use of the publicity-generating potential of the Internet, requiring contestants to post links on forums, blogs, and websites and collecting votes from the users of those sites. Many of the early fan-made trailers and later other viral videos and commercials circulated via YouTube, and captured media attention there with such titles as: "Cats on a Plane" (which was featured in Joel Siegel's review of "Snakes on a Plane" on
Pappus's hexagon theorem Pappus's hexagon theorem In mathematics, Pappus's hexagon theorem (attributed to Pappus of Alexandria) states that given one set of collinear points "A", "B", "C", and another set of collinear points "a", "b", "c", then the intersection points "X", "Y", "Z" of line pairs "Ab" and "aB", "Ac" and "aC", "Bc" and "bC" are collinear, lying on the "Pappus line". These three points are the points of intersection of the "opposite" sides of the hexagon "AbCaBc". It holds in a projective plane over any field, but fails for projective planes over any noncommutative division ring. Projective planes in which the "theorem"
