The McDonald’s McRib sandwich, a legendary, limited-edition boneless pork sandwich, shaped to look like a rack of ribs, is back.

But how much do you really know about it?

Here are six surprising, and shocking, things you may not know about one of America’s favorite now-you-see-it, now-you-don’t wonders:

1. Why was the McRib created in the first place?

Rene Arend, McDonald’s first executive chef and inventor of the Chicken McNugget, also a French-trained chef who honed his talents at the Drake Hotel, has explained in interviews that the McNugget was so popular when it was first introduced in 1979 that demand quickly outmatched their chicken supplies. Franchises that didn’t have the Chicken McNugget needed something new to sell, and so Arend went back to the test kitchen, and emerged from it with the McRib.
