The core food groups of a 5-year-old kid are Pop Tarts, pizza, corn dogs and chicken nuggets. But mind you, they aren't just any chicken nuggets. They have to be Chicken McNuggets. And, as a good father, I must oblige and dine accordingly. (As in, he gets the 6-piece, and I get the 20-piece.)

So this morning, I learned that Chicken McNuggets aren't just random shapes. The distinctly-shaped piece actually have names.

According to Business Insider, here's what each of the four Chicken McNuggets are called:

  • Bone
  • Ball
  • Bell
  • Boot

So the next time you order up the McNuggets, take a closer look and see if you notice the shapes.
