Just when you think you know everything about McDonald's, you find out a new trivia fact that BLOWS YOUR MIND. 

You might have noticed this without really thinking about it, but Chicken McNuggets only come in four shapes . . . and McDonald's has official names for all of them.  Here are the four McNuggets:

 

#1.)  Bell.  This one is shaped like a bell . . . narrow on top, wide on the bottom.

 

#2.)  Bone.  This is the name for the one that looks like a slightly lumpy rectangle.

 

#3.)  Boot.  Boot shaped, obviously.

 

#4.)  Ball.  This is the circular one.
