America's a big place and it's also kind of weird in some ways. TopTenz has collected ten strange things about the US that might actually seem normal to Americans, but seem very odd from an outsider's perspective. For example, beastiality is still legal in nine US states but premarital sex or co-habitating before marriage is still illegal in four states. Also, 30% of Americans would rather save money than get necessary medical treatment.
Perhaps most strangely, the American government has official advice for those who want to report Elvis sightings.
So check out the whole list at TopTenz.
