Segway Wank!
It all starts when somebody posts to a completely unrelated forum that he hates Segways and wants to kill their inventor, and tosses in some Bush-bashing for good measure. Some people try to keep it light-hearted by mentioning a Sluggy Freelance storyline involving Smegways, but it is quickly lost in people bitching that Segways are pure apathy, and will destroy the poor oil industry tycoons, and bring about the end of the world as we know it.
It's not a very long wank or a very intense one, but I thought it was notable for, if nothing else, the pure ridiculousness of it.
