Conan was taping its Monday episode with guest Will Arnett when news broke that Robin Williams had been found dead in his home in California from an apparent suicide. After hearing of Williams' death, the show taped an additional segment after shooting for the episode had wrapped, where O'Brien—visibly shaken and resisting a trembling voice—expresses his condolences, grief, and shock. When he announces the news, you can hear members of the audience gasp. "I'm sorry to anyone in our studio audience that I'm breaking this news," O'Brien said. "This is absolutely shocking and horrifying."

Comments have been turned off on this post because some asshole keeps posting gore and porn GIFs and we don't have an adequate way to stop him. Sorry.
