I only eat pig's liver, that's all the offal I can
handle.
WHY eat something that shit passes through? I mean, if
they don't clean it thoroughly, YUUUUUCKS!!! "What's that
blackish, sticky thing inside my intestine?" Yuuuuuuucks!!!
Even chicken feet... chicken step on all manner of dirt and
shit, and then we put it into our mouths to contort the shape of
our mouths and suck the stubborn stools out of every crevice of the
chicken feet! Yuuuuuuuucks!!
I might just eat these things in times of war and scarcity, but
in times of abundance, no way, José! 
#1 Those offals are well cleaned from the plant already
#2 For chicken feet, you have to remove the thick and hard outer
layer skin which is what touches the shit and crap. The soft parts
you eat dun come in contact at all with the ground. It's like
removing a banana skin you know
#3 I hope you don't like pig trotters :P
