Matt Damon appeared on The Tonight Show last night in support of The Bourne Ultimatum, and his was a textbook example of how to be a great talk show guest, especially hilarious for Los Angelenos. After poking fun in good-natured fashion at Ocean’s mates George Clooney and Brad Pitt over the fact that his recently received star on the Hollywood Walk of Fame was the first amongst the three, Damon talked about the days when he first moved to L.A., and lived with Ben Affleck and another guy in an apartment complex on Cherokee, just off Hollywood Boulevard. According to Damon, they ran a contest to see who could make it to the corner store and back without being offered crack — but offered so nicely, Damon made a point of emphasizing. (Jay Leno also then shared a funny story, about how his star on the Walk of Fame is near where he was once arrested for vagrancy, and sleeping in his car.) The second segment found Damon pleasantly suffering some paparazzi-snapped surfing photos of a recent vacation in Hawaii with Affleck and the guys’ wives. They finally got around to showing a clip from the movie, of Jason Bourne hot-wiring a car and driving off the roof. Good times…
