Robin Williams' death has hit Hollywood hard, with many of the beloved actor's colleagues and longtime fans expressing their grief on social media. Conan O'Brien chose to do so on air, before wrapping up his Monday night show.
Conan, Andy Richter and guest Will Arnett bid farewell to the comedic wonder they all had the pleasure of working with, in a moving tribute:
Absolutely stunned to hear the news about Robin Williams. It's unimaginable to me that we've lost such a genuinely funny and sweet man.
