If you say "fued" out loud like it's spelled, it sounds like "food"...and Oprah's fat.
I also find this whole "feud" between the two to be hilarious. Oprah needs to learn how to not take herself so seriously. Whenever I hear of stories like this, I'm reminded of that SNL skit where Tim Meadows was Oprah and was being carried around on a bed like an Egyptian queen, while the men carrying her chanted, "Ohhhhhhhprah. Ohhhhhhhprah." Then she referred to herself in the third person a whole lot, and called herself, "The Oprah."
I picture her a lot like that in real life.
