To take it even further, "Sons-in-law are correct". It's one of my problems with English, when a word clearly refer to more than one, shall I use "is" or "are". Like "the group of people", "the rolling stones" or "everyone" when I know for sure that "everyone" in deed many people. In Norwegian we only have one word, "er", which translates into "am", "are" or "is" depending on the context. Usually I know what to say, but not always.
