Friday is National Grammar Day, an unofficial annual celebration of language and good writing. Teachers, students, authors and editors observe the holiday every March 4 in the United States.

It's a good-natured observance where people share tips about how to improve grammar and jokes about those who struggle. Even the date itself is a grammar joke. "It’s an imperative: March forth on March 4 to speak well, write well and help others do the same," according to the Examiner.

Writing Forward suggests spending your National Grammar Day by looking up grammar tips, browsing themed e-cards or checking out some famous typos. 

"It should be a lighthearted day of exploring and learning," Mignon Fogarty, who wrote "Grammar Girl's Quick and Dirty Tips for Better Writing," told the Chicago Tribune in 2012. "It's a day to get everyone thinking about language and all its quirks and frustrations and fascinations."

On National Grammar Day 2016, check out a few of the internet's best language jokes, collected from Grammarly, GoodReads and Alpha Dictionary, the last of which includes phrases from Paul Ogden, Doris Britt and Reba Prater:
