McNugget Shapes Have Names

I have always known that McNuggets only come in 4 shapes. Recently I got a 4 pack of McNuggets and got a bonus 5th nugget. Jim Gaffigan talks about God giving bonus fries. But a bonus nugget? Amazing!

Its shape looked non-standard though. It was more of a sphere than a flattened piece of processed chicken.

Wikipedia says there is a name for each shape: According to McDonald's, the nuggets come in four shapes: the bell, the bow-tie, the ball and the boot.

Upper left - boot, upper right - bone, lower left - bell, middle right - bone, lower right - sphere?
