Jelly fish I have had...meh...no big deal there...chicken and/or duck feet I have refused. I have has cow cartilage (served cold), pig intestine and the lung of some other animal and a few things I did not want to know where it came from... I also discovered Mrs. Wu has absolutely no idea what spicy means.... I depended on the oldest to tell me what was spicy and what was not, and with him away at college the youngest has taken up the job..... once in Chinatown there was a street vendor selling a grilled/smoked ribs. Mrs Wu was all excited and bought one, she had not had these since she left China. Gave me one to try, I asked her if it was spicy, she said a little.... I took a bight and that is when I discovered it was not barbeque sauce...it was napalm....she as told me things were not spicy when they were and she was surprised they were and told me things were a little spicy when they were much the same as eating fire.... there have been a few times she told me it was to spicy and I should not eat it....I Figure those were coated in acid.....
