"Americans love wearing shorts, even when it's not all that warm outside." -- Nelly, Spain
"North Face fleeces." -- Jacqui, Germany
"Ill-fitting T-shirts that showcase somewhere they've been or a feat accomplished, like 'Milwaukee Marathon' or 'Chicago Zoo' -- something embarrassing Europeans wouldn't dare be spotted in. Then on party night, American girls wear pounds of makeup." -- Susan, Netherlands
"Americans are the ones wearing fanny packs -- though I think it's because they want to keep an eye on their wallets." -- Elio, Venezuela
"Americans are used to big portions in restaurants and cafés. So when I see someone walking around Europe with more than a half-liter of coffee, that person is likely American." -- Matt, Spain
"Americans go out and get college-girl drunk -- it's a big cultural difference. In Greece, we care a lot about what people think, so we grow up trying to do everything in certain ways. Plus, there was never a drinking age here [until recently when they made it 18], so as teenagers, we never felt the need to get wasted because we easily could if we'd really wanted to." -- Stavros, Greece
"I'm not saying that all Americans are overweight, but the overweight people I encounter here tend to be American." -- Barbro, Sweden
"Their beautiful teeth!" -- Jonathan, UK
"If there's a girl on the beach in a bikini with six-pack abs, my first thought is, 'she's American.' Spanish women don't aim for that look. It’' custom here to eat reasonably healthy with the exception of having a beer with every meal, but since we walk everywhere, we don't really gain much weight. Americans, however, work out to get toned." -- Beatrice, Spain
