Now, come on, do we really need the inverted commas? There are plenty of people famous in the US that no British person will have heard of. Are they "celebrities" too? I mean, I get that you're "trying to be funny," but so often it just comes off as snide: "oh look at this quaint little country and its weird little ways! How sweet the way they're not awesome American!" Can't we talk about differences between counties without mockery? Can't we all just get along (sniff)?
