Cow Brain Tacos

Author and frequent TV guest Eddie Lin got his start in extreme eating at age six when his mother prepared pork brains with sesame, soy sauce and green onion -- and Lin found it to be creamy and delicious. But he says, eating cow brains like seen above can be incredibly dangerous. (If infected with mad cow, it can lay dormant and you can die 50 years later.) Lin says, "It'd be the most regretful meal you ever had."
