Please forgive me for sounding stupid but why on earth would anyone shoot air into the head of a pig and let the brains fall out.

I must be completely clueless here. I just walked over to Alan and asked "Forgive this question, but have you ever been around pigs brains in a slaughterhouse. The look on his face was priceless.

But honestly, why would anyone work there, and what is the end result??

I'm very serious here.

Is this a food item or something??

Thanks.
