August 11, 2014 was a dark day for the world as beloved Robin Williams passed away unexpectedly in an apparent suicide. Have a look at the emotional tribute Conan O’Brien paid on his talk show, along with guest Will Arnett.

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.
