Thought that this was a rather funny one. There is actually a company called Barf which produces hand washing powder for cleaning clothes. Not exactly the best name to chose from...
But I should add that it's not something I picked up in an English speaking country (although the descriptions are obviously in English, making me at least wonder why the company didn't know about the meaning of "barf"). Extra points for anyone who knows in which country you can buy it :)
