Chicken... balls

This afternoon I had lunch at KFC. Upon tearing apart the skin from a piece of chicken, I saw...

Balls

Well they might not be rooster jewels, but they certainly were scary to think that I nearly ate these.... balls. They're of a bright yellow and somewhat soya bean-shaped.

I didn't pay attention to them until I finished my meal when it struck me that they could be some cancerous growth or just... balls.

My friend assured me that they're just batter.
