"They and themselves" is the more common way of saying it nowadays, but it's incorrect grammar by the old established rules that I was taught when I was in school.

To say to a dog "Lay down!" is incorrect also. It should be "Lie down!", but practically every North American now says "lay down" for some reason when he (or she*) (*happy now?) means "lie down".

It seems that incorrect grammar is becoming more generally acceptable lately than correct grammar. Interesting. Could this be part of the American Dream of "just plain folks" who talk "plain" being better people than "eggheads" and "liberal intellectuals" who use proper English? Why do plain people talk "plain" when they used to talk plainly?

"Where have all the adverbs gone, long time passing..." (grin)

I wonder if it will soon be considered more acceptable to say "nookyular" than to say "nuclear"? (new-clear) Could be. I mean, hell, the President says nookyular and so do a majority of the people who voted for him and even maybe of people who didn't. I figure nuclear is on its way out.

Then there's February! Can ANYONE out there pronounce it properly? It's Feb - ROO - ARY. Now tell me that's hard. Is it really that hard to say Feb - ROO - ARY? Well, gosh, it must be hard, because only one in a hundred people I know can manage it. Maybe we should just drop the "r" and make it Febuary instead?

Oh well, it's all essentially arbitrary anyway. Customs change and so does language, as is evident when one reads Shakespeare or the King James Bible.
