Hang out with some hooligans causing trouble during the Olympics in London. Take the Chunnel to France. Get thrown out of a casino in Monte Carlo. Climb Mt. Etna when smoke is coming out of the top. Get a huge bottle of ouzo and watch the meltdown of the cradle of civilization in Athens (sit near the window if you feel lucky). Strudel with cream sauce outside in Berlin. Go skiing in Dubai. Thailand has already been covered by others. Apply same logic to Phillippines. Spit on the street in Singpore and see if anyone notices. Buy a suit in Hong Kong. Go to an Apple factory in China. Eat kimchi chigae and drink 4 bottles of soju in Seoul--then go to noraebang and sing the Flintsones song. Ride the subway in Tokyo. Go to Giovanni's shrimp truck on the North Shore---Matsumoto's shave ice for dessert---get the beans for a topping---trust me. Wrap it up with salmon and halibut fishing in Alaska--insist that your 100LB fish cooler wrapped with duct tape is a carry on.
That's all I can think of off the top of my head.
