Our texts, emails, tweets and other forms of communication may have shrunken in size, but there is no excuse for poor grammar — especially punctuation.

National Punctuation Day is Sept. 24. To celebrate raise awareness we've gathered some of the funniest, most unfortunate examples of poor use from around the world. Take a browse though the gallery, and then brush up on your grammar skills here.
