No, that subject line is not disguised profanity, but a tribute to National Punctuation Day, which is today. This year marks the fourth celebration of principles that must be hallowed by punctilious teachers, editors and other meticulous individuals everywhere.

As the name would suggest, National Punctuation Day is meant to remind people – both big and small – of the importance of proper punctuation; indeed, we all could probably use a reminder every now and then! So remember: Watch those comma splices…and try not to overindulge in exclamation points.

Oh, and for some samples of what not to do, check out photos of "annoying punctuation gaffes" on the site dedicated to the cause.
