Crosses the Line Twice: Pretty much the whole point, although the APEC incident and the Eulogy Song are most famous.
Not to mention the Make A Realistic Wish Foundation.
Crowning Moment of Awesome: Brazenly driving a blatantly fake motorcade into the most high-security area in Australia during the APEC summit, pulling up outside the hotel where George Bush was staying and having Chas get out of the car dressed as Osama Bin Laden!
And then they arrested the other guy!
The guys that weren't part of the motorcade (and so, weren't in jail) approached the same area the next day in "Play School cars" (cardboard boxes with paper dinner plates for wheels), claiming to be a motorcade and asking to be let through please. You know, just to rub it in their faces even more.
