Have you ever eaten a son of a bitch?

I was flicking through one of my recipe books today and I came across a reference to a old American dish called "son of a bitch".

Basically it's a stew made from a mix of offal from a milk fed calf mixed with half digested milk from it's intestines called marrow gut. It was a popular dish with a lot of variations but the marrow gut was considered essential.

I was wondering if people in the states still eat it and has anyone here tried it?
