Ive been rewatching Grey's since the beginning, and in season 3 Izzie eats everything in the fridge and goes on about eating a tub of butter. Is that a thing? Even people who over-eat..Ive never heard of anyone eating a tub of butter??!
I'm not sure, it could be a metaphor. I know sometimes when I crave sweets and there is nothing in the house, I make cookie dough, with butter, flour, sugar and eggs,
I don't know. She said she ate everything in the fridge including a tub of butter. Then later in the episode she was like..I believe if I eat a tub of butter in the middle of the night and no one sees me then the calories don't really count. *squick* the thought of eating just plain butter by itself?! Oh man, makes me gag.
