I can trace my roots back to good old Black Pudding....
I used to enjoy that breakfast food until I realised that it contained more blood than I did.
Edit -I was a little whipper snapper at the time, my Grandmother being the true English woman that she was, used to sit me down, put the plate in front of me and say 'here's your breakfast c*ck'. A very gender confusing English term of endearment.
