The day Robin Williams allegedly committed suicide on Aug 11, his good friend and co-star Billy Crystal wrote briefly on Twitter that he has "no words" to describe his feelings. But when Crystal paid tribute to the "Mrs Doubtfire" actor at the 66th primetime Emmy Awards on Monday, his words flowed appropriately. Not only did the actor give a beautiful and a heartfelt tribute to Williams but he also called him "greatest friend you could imagine" and a "beautiful light" that will "shine on us forever."

The emotional tribute to Robin began by a very appropriate song "Smile" by singer Sara Bareilles during the In Memoriam section of the show. Then entered Billy Crystal who stood in front of a huge picture of the legendary actor Robin Williams, whose death has shocked the world.

"He made us laugh hard, every time you saw him. His brilliance was astounding... I used to think if I could just put a saddle on him and stay on for eight seconds I would be OK," said the actor as he began his tribute.

"As genius as he was on stage, he was the greatest friend you could imagine. It's very hard to talk about him in the past, he was so present in all our lives ... for 40 years, he was the brightest star in the comedy galaxy...but while some of the brightest of celestial bodies are actually extinct, their molten energy long since cooled, miraculously, because they float in the heavens so far away from us now," he further revealed about Williams.

Crystal concluded his heart warming and emotional speech by acknowledging the fact that though Robin is no longer alive, he will continue to be in the lives of his loved ones. He compared the late actor with a "beautiful light will continue to shine on us forever, the glow will be so bright it will warm your heart."

Crystal also added that it was very hard for him to talk about his good friend in past tense because he has been present in the lives of all his loved one always. The organisers at Emmy Awards then played a wonderful video of Robin Williams in his comic appearance. See the video below for a more memorable experience.
