WATCH: Jimmy Fallon pays a tear jerking tribute to Robin Williams

Jimmy Fallon pays a heartbreaking tribute to Robin Williams on the Tonight Show.

We are not going to lie this brought us to tears

Just witnessing how genuinely upset the TV show host is in his opening segment - even stopping to catch his composure - would move anyone.

“He was one of a kind — he was one in a million,” Jimmy said close to tears.

Jimmy then continues to introduce a hilarious clip of Robin’s first appearance on the famous Tonight Show with host Johnny Carson.

After the clip, Fallon joined the growing group of fans paying tribute to the actor by standing on a desk, reciting Walt Whitman’s poem, Oh Captain, My Captain! — a homage to Williams film, Dead Poets Society.

Just heartwarming!
