I mean.. **** like this is bound to accidentally happen sometimes. It's not like you hear about chicken heads in chicken nuggets all the time. I don't understand why this is news worthy.
If Mcdonalds chicken nuggets weren't awful, I'd still happily buy them even if I was the person who got the Fried chicken head.
I probably would have taken it back to the McDonalds, say "hey I think I got a chicken head.. can I get a refund and some new Mcnuggets" to which they would have happily refunded me my money, and given me new Nuggets.
Taking this to the news just means whoever got the chicken head simply wants a few minutes of fame.
