Hahaha!
Unfortunately we've got a sh*tload of them in the USA. They have a whole town to themselves in South Carolina called Murphy Village. They are as bad if not worse than gypsies. They are thieves and scammers and bad, bad news. They travel around the USA scamming and burglarizing homes all over the USA. They live in luxurious houses although they have no real jobs. I doubt they even pay taxes.
They often show up in small towns offering "home improvements" like coating your driveway with used engine oil to "seal it". While they are at the front door giving their spiel, another is sneaking in your back door to steal your purse or checkbook. They are evil through and through. If anyone with an Irish brogue shows up at your door offering home improvements, call the cops right away.
