Snakes on a Plane: the merchandising
Stop press! Snakes on a Plane, officially the greatest viral movie meme ever, is already attracting unofficial attempts at commercialization in the form of Cobras in the Cockpit, a board game "based on a fictional movie" (i.e. "don't sue us") where you play the snakes.
And the meme rolls on!
