Wait a minute. This looks like rock and/or roll.

You would think that before a company puts and ad in a magazine (read by millions) or on TV (read by millions) or on a billboard (read by tens of thousands), they would have someone with half a brain check it for spelling and grammar. Or what about the sign in front of your store?

It seems like, every so often, you see a pretty obvious (to the grammatically initiated, anyway) error of some sort in places that should justify professional production. I think the one I see with the greatest frequency is the incorrect contraction of "and" joining two other words. Let me just cut to the chase and give a correct—and age old—example: Rock 'n' Roll. The first apostrophe takes the place of the omitted "a" and the second the "d."

The common error is to "forget" one of the apostrophies or simply to make the whole thing a compound word, which, of course, doesn't make any sense.

If anyone can provide real world examples of this screw up, please spread the love. Heck, while you're at it, how 'bout any good grammatical errors in advertising!
