Conan tells viewers to stop watching his show and 'turn to Dave'

Conan O' Brien already gave David Letterman a heartfelt goodbye, but he continued to show his appreciation with a small, thoughtful gesture.

During Wednesday's show, Conan was mid-interview with comedian Patton Oswalt, when he urged TBS viewers to change the channel to CBS for Letterman's final Late Show.

"Record us, but switch to Dave," Conan said, as flashing graphics appeared in all-caps, stating, "TURN TO DAVE."

Then things got weird.

"They're gone now. Now we can do whatever the f*ck we want," Conan said. Then Oswalt dumped his mug out onto the stage and laid across the desk for a Coco massage.
