David Letterman and Oprah Winfrey
The feud between Oprah and David Letterman appears to be done after more than a decade. Letterman, fond of razzing Oprah on the Late Show, will appear on Oprah for the first time ever this month. The détente has been slow to develop, though: it was 2005 when Oprah went on Letterman and said, "I want you to know, it's really over."
