April 23rd is generally considered to be a good day to celebrate the birth of England’s greatest poet and playwright, William Shakespeare. This is partly because there are no records of his birth—although he was baptized on April 26—and partly because he died on April 23 (and April 23 is St. George’s day, patron saint of England), so there is a pleasing, almost poetic symmetry about the way the dates line up.

Today is the 450th anniversary of the day Shakespeare was (possibly) born, and in tribute to his astonishing contribution to the English language, it’s time to for a challenge. One that will suit all comers, faint-hearted (1) or not.

Below there are 45 common expressions that were either coined by Shakespeare or popularized by him (at this vertiginous historical remove, it’s hard to be certain what was created and what was pinched from his immediate surroundings). All you have to do, if you truly love the Bard, is work just five of them into your everyday conversations throughout this live-long day (2).

That’s all, just five and then you’ll be fancy free (3). And because brevity is the soul of wit (4), we’ve stuck to the short ones.
