The dot `.` matches _any single character_, so that regex matches any 3 characters. – Michael Berkowski Jan 31 '15 at 20:40

And it doesn't have to be exactly a 3 character string either, because it isn't `^$` anchored. It just has to be any string at least 3 characters long. – Michael Berkowski Jan 31 '15 at 20:41
