McRibs are back! Could you be one of the lucky 10,000 to get a free one? 

If you haven't tried a McDonald's McRib sandwich, now's your chance. The boneless pork sandwich topped with heaps of barbecue sauce, onions, and pickles is back in the U.S., for a limited time. It's returning to all U.S. locations for the first time since 2012. 

To celebrate, McDonald's is giving away 10,000 for free—with a catch. You have to shave your beard. 

"So that beard you’ve so proudly grown while in quarantine or for a good cause this November…it's got to go," McDonald's press release stated. "Or it could get in the way of you enjoying a mouthwatering McRib. That’s why we’re here to tell you to shave it, and you could get a McRib on us."

McDonald's partnered with No-Shave November, a month-long campaign to raise cancer awareness, to bring the contest of a lifetime. Anyone who posts clean-shaven selfies to their Twitter or Instagram public pages using the hashtag #Shave4McRibSweepstakes will be in the running to get a free McRib. You must also tag @mcdonalds in the post. Don't have facial hair? No worries, the sweepstakes are open to all—even if you're hiding your beard with a face mask. 

What are you waiting for? Celebrate the end of No-Shave November and get a free sandwich! No one wants barbecue sauce in their beard anyway.
