In case you don't get the subject line, it's the infamous taunting of David Letterman during his monologue of the 67th Academy Awards. Incidentally, he was never asked to host again.
Over the ten years since it all began, Dave has often mentioned how daytime talk show titan (the) Oprah Winfrey "hates him" as a result of that whole episode. To add to this tension, a couple of years ago Letterman kept a public journal (as a segment on his show) where he moped out loud about not ever being invited on to (the) Oprah's show. This went on for several days and weeks, where each night he would simply write and share, "Oprah didn't call today." The only catch is that (the) Oprah did call him on it and finally invited him to be on her show. Flabbergasted, Letterman backed off and the whole matter was soon dropped.
Apparently, wonders never cease. As it turns out (the) Oprah will soon appear on The Late Show in order to end her long-standing feud with Dave. It all goes down on December 1st... be sure to set up your TiVo. I'm not a fan of (the) Oprah at all (even with my Chicago roots), but I plan on watching.
No word yet if Uma plans on joining in the reunion...
