Recently Discovered (By Me) Cuts of Beef

1. Mountain Chain-Also called mountain chain tripe, it's small intestine of a cow, in its outwardly visible paunch. My supposition is that it's a beef analog to what chitterlings, or chitlins, are to pork, I'd eat them (and may have already?!) and may now actively look for it when dining at Asian eateries. Have and/or would you eat it?

2. Pizzle- When I saw frozen packages of this organ, with its (euphemistic?) name and zigzagging like a three-dimensional maze path, underneath its plastic wrap, I got to wondering, "Is that what I THINK it is?!" It is, in fact, what I thought it to be and what you may already know it to be; that's beef penis. Testicles from the same animals are served as Rocky Mountain oysters, so it makes sense to me that their other reproductive organ would be eaten by people, too. In dehydrated form, they comprise bully sticks for dogs, so you made have given your or some else's pooch pizzle to chew and play with. But have and/or would you eat it freshly stir-fried, curried, or however else it could be prepared?
