A PIGS HEAD - HUH?

So on one of my trips to the market in Viet Nam I saw a pigs head sitting there for sale. Huh? What? A pigs head? What are you supposed to do with a pigs head I wondered? I dunno….I have no clue. How do you serve this? Cook this? What exactly are you supposed to do with a pigs head? Now I'm sure there are probably many ways to eat a pigs head but I personally have no clue whatsoever. Oh well….Because this definitely caught my attention I just had to take a photo for my many readers. enjoy! HAHA!
