OK, so today is National Grammar Day, brought to you by The Society for the Promotion of Good Grammar.
You can swing by the site and print out your card to flash at people when you find them using bad grammar. (However, prepare for some mean looks and possible physical confrontation from strangers.)
But in all seriousness, isn't it sad that there is a National Grammar Day? Shouldn't every day be grammar day? Oh, a copy editor can dream, right?
