Better cross your Ts and dot your Is, because Saturday is National Grammar Day. A holiday started by Martha Brockenbrough, an author who also founded the Society for the Promotion of Good Grammar, National Grammar Day is more than a chance to correct your friends' subject-verb agreement without seeming pretentious — it's a chance to celebrate good language and the rules that guide it.

Whether you're a copy editor, a teacher or just a reader with a good eye for grammar, here are 10 ways to observe National Grammar Day:

1. Peruse Cake Wrecks, a website that shows bakery cakes with unfortunate mistakes. It has an entire Creative Grammar section that's sure to make you LOL.

2. Read this cookie-themed lesson on when to hyphenate compound adjectives. Once you're finished and hungry, bake a batch for your friends — using a grammatically correct recipe, of course.

3. Recall the worst typo you've ever made. Then comfort yourself with others' mistakes.

4. Send your friends snarky e-cards about their grammar.

5. Buy yourself a decorative apostrophe from Bed Bath and Beyond or comma earrings from Etsy.

6. Read a book and brush up on your grammar. Then take a grammar quiz to see how much you learned. Compete against your friends to see who can get the highest score.

7. Make a newspaper blackout poem.

8. Write a grammar-inspired haiku for the American Copy Editors Society.

10. Tell your friends a grammar joke that will make them groan. Here are a few to get you started:

  • The past, the present and the future walk into a bar. It is tense.
  • What are Santa's elves called? Subordinate clauses.
  • What do you say when you're trying to comfort a grammar nerd? There, their.
