David Letterman tonight tells Oprah what is the one thing he’s taking from his Late Show office adjacent to the Ed Sullivan Theater.

Next week  is Letterman’s last hosting the CBS late-night show. On Monday, Tom Hanks is his guest, making his 60th appearance on one of Letterman’s programs, beginning with Late Night in the mid-80’s.  Tuesday, Bill Murray, who was Letterman’s very first Late Night guest in 1982, will visit Dave for the 44th time. CBS isn’t saying what’s in store for Letterman’s final night, describing it coyly as “an hour filled with surprises.”

Here’s Oprah’s first visit to Letterman’s show back in 1989. She would not appear on his show again until 2005.
