Liver for me too. Also, DH's aunt once served us cow heel soup. It must have been the greasiest food I ever tasted, but I had to gag it down.
In France with my 1st husband (not a D H) I was being adventurous and ordered something called Andouillettes (sp?), omg it looked like sausage but was so disgusting, I think it was made out of tripe. He offered to trade with me because he didn't mind it but he had ordered sheeps brains!!!! Let's just say I ordered and enjoyed my dessert!
I just remembered, in Grenada, where I lived for 2 years, they eat something called Manicou. I think it is some kind of possum but it looked like a rat to me. One very tiny taste (the size of a pea) was enough. (shudder)
