The Poop on Oprah

Oprah Winfrey gabs about all kinds of topics of national and emotional import on her show -- but the one thing she seems to be truly obsessed with is poop. As in human feces.

On yesterday's show, Dr. Mehmet Oz, Oprah's on-demand dispenser of medical info, answered the call of doody to explain the intricacies, vagaries, and complexities of poop. "More people stop me about poop than Brad Pitt," declared Oprah, explaining that her previous shows on the topic have generated considerable buzz from her acolytes.

Oz helped Oprah understand why poop is the color it is (it's because of the bile, which is brown), why it's best if it comes out shaped like an "S" (though it's OK if it's shaped like a comma or a "C"), and why some people actually produce white poop (a deficiency of bile). Oprah thought that last tidbit was definitely a little kaka-eyed. "I have never heard of white poop in my whole life," said a skeptical O.

But leaving her Midtown hotel recently, the Queen of All Media almost looked as though she might have to attend to a little, um, fecal matter right there in the middle of Manhattan! You go, girl!
