Jimmy Fallon has debuted a "House of Cards" parody which he teased on Monday, August 11 with a picture on Twitter. Aired on "The Tonight Show Starring Jimmy Fallon" on Tuesday, the new digital short had Fallon taking in the role of Kevin Spacey's Frank Underwood, over-explaining things into the camera.

He received mysterious text messages and arranged a meeting with the unknown sender on the subway. It was later revealed that previous "Tonight Show" host Jay Leno was the sender and he still held grudge as he pushed Fallon into the railway.

The spoof also featured Ellen Barkin as the parody version of Robin Wright's Claire Underwood.

Early in the episode, Fallon took some time to pay tribute to Robin Williams, who passed away on Monday. "Before we get into the show: We, like all of you, we were shaken up a bit last night, when we learned that genius comedian/actor Robin Williams passed away," the former "Saturday Night Live" member said to his audience.

"He was one of a kind - he was one in a million. He was like unbelievable. If you ever saw this guy's standup, you wouldn't even believe it. If you don't know his standup you should YouTube it right now and just watch it. It was amazing. he was funny and he was fast and he would weave in and out of characters."

He continued, "And you'd watch him and you would cry laughing, and you would think, 'I'm never going to see anyone like this human ever!' It was just amazing. His brain was always thinking, 10 steps ahead of what he was thinking. He was the Muhammad Ali of comedy."

He also introduced a clip of Williams' first appearance on "Tonight Show" when Johnny Carson was the host. Fallon then stood on his desk to reenact a scene in Williams' movie "Dead Poets Society", reciting part of Walt Whitman's poem, "Oh Captain, My Captain!".

Later that night, Seth Meyers remembered the late comedian on his own "Late Night" show. "We found out after our taping last night, so I just wanted to take a moment tonight - I'd like to say on behalf of everyone at 'Late Night' - I would just like to send our condolences to his family," he said.

"The saddest part of this is Williams was battling depression, and if there is anything we can do to honor his memory I would hope it would be to use this opportunity to educate us more about this terrible affliction. So we just want to say that we miss Robin, but we're also very lucky to have had him at all. So thank you to Robin Williams, I guess."
