Not to mention how totally gross it smells!!! I had to carpool with a guy once for 50mins who had his dinner in the back of the car - it was cooked offal, and I had the window open the whole way. It was 7pm, in the middle of winter (about 3-4deg) and I didn't care. The smell turned my stomach!!
I have eaten a teeny tiny amount of brains - but there is no way I could eat liver or kidney - PUKE!!!
