As Dotsie said, it has come Across the Pond is now entrenched in the Brit workforce, just as we planned, woohahhahahahaha!!!!
But, this sort of thing is used all the time in offices across the States, especially dot.coms. In fact, this is probably one of the least sophisticated of these weapons. Others use electronic foam missile launchers that are controlled by a computer of iPhone. Hell, no one surpasses us Americans in finding new ways to waste time at work!

Oddly enough, one of my favourite things to buy in the US was originated in the UK, but are much more popular overseas than in Britain. Callard and Bowser Altoids, come in all sorts of flavours, but I like the cinnamon ones best.
There is a chain of grocery stores in the US called Trader Joes. They do tins of vanilla flavoured mints that I love. You can also get really good Swiss, Belgian and German chocolate from there.
