Haha funny story. My grandfather used to drive a truck and one night when he came home from driving, he was hungry and the rest of the family, (Dad, his brother and two sisters, and grandma) were eating what appeared to be hamburgers. The kids weren't touching their food but grandpa was inhaling the 'hamburgers'. Soon after that, grandma said to the kids, "Come on kids. Eat your cow brains."
Dad said grandpa just stared off toward the wall, and left the table and went to bed.
but yeah. My grandmother had to eat everything in the cow during the great depression.
