A few years ago, there was a couple of people from the UK going on holiday to somewhere in the US. They joked (on Twitter andn/or Facebook) about how hard they were going to party, using some unfortunate slang terms. Something about setting on fire a whole city (or something like that) a whole city, it was obviously a figure of speech. As well as digging up some celebrity's grave (either Marilyn Monroe or Elvis, I forget).

Anyway, they had paid for their tickets to the US, crossed the ocean, were stopped and sent back (at their own cost of course, I bet travel insurance didn't cover this).

Sorry that I don't have the link to this story.
