A recent press conference for chess champion Gary Kasparov* was interrupted by a very special vehicle: A hellicockter. A remote controlled helicopter shaped like a penis suddenly flew in front of cameras, only to be swatted at and stomped on by some very specialized security personal. See the above video and scroll to the 20 second mark.
This is pretty much the best prank I've ever seen, and could only get better if it suddenly became a phenomenon and all sorts of genitalia vehicles started showing up at press conferences and public events. Perhaps the Obama campaign trail could be followed by the Hellicockter? Genius in my opinion.
*I did a google image search of this guy and it's kind of humorous how many variations of this pose he has.
