I was on a European business trip about 7 years ago and was flying with some European colleagues from Basle, Switzerland to Paris. As we were arriving into Paris, one of my colleagues pointed out that the Eiffel Tower was in view on the left side of the plane. She asked me if I'd ever seen it before. I told her I had only seen the Eiffel Tower in Las Vegas. Another passenger who I guess was from France smiled with a mixture of humor and derision. He was thinking something along the lines of, "How dare you compare the Eiffel Tower in Las Vegas with the real tower in Paris?!?!"

I was very amused by that.
