There are a lot more than six, but this is a start.
I especially like the mental image produced from the idea of people stuffing handsful of Crisco into their mouths.
My mother used to break Oreos in half, eat the chocolate side, and give me the side with the filling, which I didn't particularly like, but it was the only way I could get the other chocolate half. Thanks, Mom.
Edited to add: It looks like Oreos no longer has trans fats in their Oreos. Looking at their list of ingredients, however, I still don't think I want to eat them.
