They make a really good stock for soups and used to be free, now the price is starting to climb rapidly.
Anybody remember when the butcher gave away soup bones, liver, tongue, heart, slabs of fat and other things like that for free?
I remember back when most people would scoff at chicken wings. They used to be dirt cheap till the bar crowd discovered buffalo wings.
There was also a time when no-one I knew would eat Chinese food. Well except the Chinese of course.
There was an asian contestant on Fear Factor who not only ate all the wierd stuff that the others gagged at. He asked Joe Rogan for the leftovers that one of the others refused to eat then he ate them because as he said , He was hungry.
